About Diamonds+

Purchasing a diamond, online or in-store, can be difficult. With Four Mine’s diamond education guide, you’ll have the tools and tips required to buy the best diamond available for your budget.

Every diamond is unique because a variety of diamond attributes define the diamond’s sparkle, brilliance and shine. Ultimately, the most important characteristic of a diamond is its visual appeal. If you love how a particular diamond looks, other attributes do not matter.

Shape+

The most visual characteristic of a diamond is its shape. This is the first thing you must choose when selecting a diamond. There are 9 popular diamond shapes used in jewelry and engagement rings: Round, Princess, Cushion, Oval, Emerald, Pear, Asscher, Radiant, Marquise.

STYLE: classic, elegant, sparkling

Most popular and researched shape - When cut well, the proper reflection of light, the potential of brilliance and brightness is maximized. The round brilliant cut diamond has 58 facets. Its 58-facet cut, divided among its crown (top), girdle (widest part) and pavilion (base), is calibrated through a precise formula to achieve the maximum in fire and brilliance. When cutting a rough stone, more is lost in shaping a round diamond, so the cost of each carat retained is higher. Over 75% of the world's diamonds are Round Brilliants.

STYLE: trendy, beautiful, angelic

Second most popular shape - prefered in square shape but available in rectangular shape also. The princess cuts that are slightly rectangular tend to be lower in cost. This cut requires more weight to be directed toward the diamond's depth in order to maximize brilliance. Depth percentages of 70% to 78% are common. Ideal square ratio ranges from 1.00 to 1.05. A princess cut should always be set for 4 prongs protecting its corners from chips. It is ideal for long fingers and wedding bands. It has 57 or 58 facets and is known as square modified brilliant cut or Rectangular Modified Brilliant when the ration is greater than 1.10.

STYLE: romantic, graceful, sophisticated

Cushion cuts blend the energy of a round brilliant with the symmetry of a radiant cut. It's romantic appeal is reflected in its larger 58 facets and rounded, squared corners. Also known as the "pillow cut," the cushion cut’s larger faceting augments the diamond's brilliance. Larger facets can show clarity inclusions, so evaluate the location of inclusions by examining the certificate's diamond plot. Cushion cuts are popular in both square and rectangular shapes. Square cuts are generally a bit rarer, but do look more symmetrical in an engagement ring. Cushion cut diamonds have great fire (the light that is reflected out of a diamond in a rainbow of color).

STYLE: modern, bold, glamorous

Emerald cuts represent unification, as they are well proportioned and bring out the pure brilliance of a diamond. Also known as "step cut" because of the layered faceting, the emerald cut possesses unique appeal with symmetrical sparkle. The faceting is minimal and simple, and therefore tends to show inclusions. The diamond has 58 facets, roughly 25 on the crown, 25 on the pavilion, and 8 on the girdle with 3 rows of bottom steps and three rows of top steps. An open setting can also show the diamond's color, so closed or bezel type settings are recommended with lower colors.

STYLE: fashionable, innovative, adventurous

A natural variation of the round brilliant, the distinctive oval shape possesses similar sparkle in its elongated body. The oval shape is a perfect complement to long fingers. It can mask inclusions and color similar to the round brilliant, while it's shape elongates the fingers. Shorter ovals can look like cushion cuts, so we recommend a ratio of 1.33 to 1.66. Oval diamonds appear to be larger than you expect because they often have a greater surface area than a round diamond of the same weight. Many Ovals can have a “bow-tie” effect. This happens when light doesn’t bounce back in the middle of the diamond because of the way the diamond is cut. You can only gauge the “bow tie” effect visually. Oval diamonds are perfect for people that like round shaped diamonds but prefer something unique.

STYLE: fiery, diva, provocative

A beautifully symmetrical, non-traditional cut, the radiant cut combines the brilliance of a round and the purity of an emerald cut. Trimmed corners give it versatility among all kinds of jewelry, especially engagement rings. The faceting of a radiant cut gives it a fiery look compared to a princess cut, while maintaining soft, cut corners. The radiant fuses the plus points of other popular diamond shapes. The rectangular radiant cut is an excellent option for buyers who like the emerald cut shape, but want something with the brilliance of a round. A ratio of 1.00 to 1.05 will create a square shape, and from 1.30 to 1.50 will produce a rectangle.

STYLE: balanced, vintage, creative

The asscher cut is (also a step cut diamond like the emerald cut) is a blend of the princess and emerald cuts with X-shaped facets from its corners to its center culet. The brilliance of its faceting can mask certain inclusions and lower color grades. Asscher cut diamonds have a clean balance, visual appeal, and can reflect clarity inclusions and color. Higher grades in both categories are generally recommended. The step cut emphasizes the clarity of the diamond, and it is ideal for showcasing higher clarity diamonds. Asscher cuts are a popular shape that was developed during the Art Deco Period. Suggested Cut Ratio: 1.00 to 1.05 for square proportions.

STYLE: dramatic, moving, joyful

The marquise cut is a classic and historic diamond that resembles the delight of a smile. The marquise is a variant of round and pear shaped diamonds, and like the oval is a perfect complement to long, slender fingers. The marquise cut's elongated body can make its appearance larger than its actual carat weight. It is an excellent cut to show the impression of long, slender fingers. Suggested Cut Ratio: 1.75 to 2.25 is the ideal shape.

Marquise

Pear Shaped Cut

STYLE: contemporary, unique, gentle

The pear shape diamond is artistic due to its many stylish variations. With 58 facets, light dances through the diamond similar to a round brilliant, maximizing sparkle. It's teardrop appearance leaves a lasting impression. The pear shape’s body allows the wearer the option of pointing it up or down. Its faceting often masks inclusions, and those found near the point tend to be less visible. Pear shapes can be wide or elongated, with longer pear shapes providing a slimming effect on fingers. Suggested cut ratio: 1.5 - 1.7. Most flaws such as naturals, and extra facets are at the point of the diamond. Always set the diamond with a prong covering the point of the stone to prevent any chipping.

Carat+

Key Points

  • The most visible attribute of a diamond
  • Carat is a measure of the diamond’s weight. Weight represents size
  • Size is evaluated by the measurements of a diamond (length x width)

 

Sizing & Rarity

  • Diamonds come in a variety of sizes. As the size increases, the rarity of diamonds increases. Therefore, the price of larger diamonds is greater than smaller diamonds.
  • Diamonds have critical weights that manufacturers use as cutting guidelines. Therefore you’ll find many more 1.00ct diamonds than 0.99ct diamonds. The price of the diamond substantially increases at each critical weight.
  • The critical weights are: 0.30ct, 0.40ct, 0.50ct, 0.70ct, 0.90ct 1.00ct, 1.50ct, 2.00ct, 3.00ct, 4.00ct, 5.00ct, 10.00ct.

 

Comparing Sizes

  • To truly understand the diamond’s size, evaluate the measurements. Well cut Round diamonds have less depth than well cut fancy shaped diamonds (diamonds other than Round). For example a 1.00ct Round diamond will have ~6.40mm length/width vs a 1.00ct Princess diamond, which will have ~5.50mm.
  • Visually, it is very difficult to discern the difference between diamonds that vary 5% - 10% in carat weight. For example, 0.95ct vs. 1.00ct.
  • Check out our diamond size chart to compare a variety of sizes across the major diamond shapes.

 

Cut+

Key Points

  • The sparkle, fire, brilliance and overall visual beauty of a diamond.
  • Cut is the proportions and angles of a diamond.
  • A measure of light performance as light hits a diamond.

 

Grades

  • Excellent: Highest grade representing the top diamonds in the world. Diamonds with an Excellent cut grade are masterfully crafted and precisely cut to unleash the maximum sparkle and brilliance of a diamond. Little or no light leakage occurs as light passes through a diamond.
  • Very Good: Very well cut diamonds that capture almost all the potential of the diamond. Very brilliant with minimal light leakage. Diamonds cut often intentional cut to achieve a Very Good grade so that can improve the other characteristics of the diamond such as Color, Clarity or Carat.
  • Good:Well cut diamonds that capture light and possess high degrees of sparkle. Good cut diamonds have some light leakage, but overall shine bright. These diamonds can have noticeably larger or even smaller measurements than perfectly cut diamonds of the same shape. Cutters may intentionally cut to Good proportions to achieve a particular look or style.
  • Fair & Poor: Diamonds with significant light leakage earn a Fair or Poor grade. These diamonds tend to leak noticeable amounts of light from being too deep or shallow in height. These have little brilliance and are less visually appealing. Fair or Poor cut diamonds do not meet Four Mine’s minimum light performance criteria.

 

Manufacturing

  • With cutting edge manufacturing technology, a diamond’s cut grade is rarely a surprise not is it an error by the diamantaire. A diamantaire’s initial goal is to preserve weight. Therefore, he/she may intentionally sacrifice a little light performance in the interest of achieving a higher carat weight.
  • Diamonds today are cut by machine and laser, but polished and faceted by hand.

 

Color+

Key Points

  • Color is based on overall body color of a diamond.
  • Color is determined by the “lack” of color in a diamond; less color a diamond has means higher the color grade.
  • GIA developed the color grading system which ranges from D - Z.

 

Determining the color of a diamond

  • The loose diamond is flipped over, table side down and is compared to a Diamond Master Set to determine its color by a trained observer.
  • To ensure an accurate diamond grade, proper lighting and special equipment is necessary to prevent distractions.
  • Color is more noticeable in larger diamonds and in diamonds with fewer facets such as Emerald and Asscher cuts, and, color is less noticeable in well cut diamonds and in diamonds with more facets such as Round and Princess cuts.

 

How Does it affect the price?

  • Some diamond colors add to their value, often significantly.
  • The price difference between each color grade (all else being equal) ranges from about 3% to more than 25%.
  • For the purist, a D – F color diamonds are ideal. For a more budget-conscious decision, consider an I – K color.
  • Purchasing a lower color diamond concedes only small visible differences, but the savings can be very noticeable. The most noticeable cost difference is often from G to F color grades. The most popular color grade is a G color with H color closely behind.

Color Grading System

  • D, E, F - Colorless range - higher premium for these diamond and have no color, color is in the purest form of white.
  • G, H, I - Near Colorless - Most popular range with consumers and still face up white when looking at the diamond from the top.
  • J, K, L - Near Colorless - Good value but can see slight tints and hints of yellow in the diamond.
  • M - Z- Noticeable Yellow - Noticeable yellow color can be seen from the naked eye.

 

Clarity+

Key Points

  • The number and size of microscopic imperfections found within a diamond.
  • Clarity characteristics can affect light performance and diamond sparkle, and rarely ever affect the structural integrity of a cut and polished diamond.
  • Most imperfections are not visible without at least 10x magnification.

 

What are they?

  • As diamonds grow over millions of years and rise slowly toward the Earth’s surface, they naturally develop tiny imperfections. These imperfections are commonly referred to as inclusions or blemishes by gemologists.

 

Grading

  • The greater the number and size of inclusions, the lower the clarity grade. The lesser the number and size of inclusions, the higher the grade. The differences between each grade are minor, but the price differences are significant.
  • FL, IF: Flawless, Internally Flawless. No internal imperfections exist. Extremely rare and valuable, these represent less than 2% of the world’s diamonds.
  • VVS1, VVS2: Very, Very Slightly Included 1, 2. The imperfections are extremely difficult to identify, even under 10x magnification. Very rare and highly valuable. Less than 5% of the world’s diamonds are VVS clarity.
  • VS1, VS2: Very Slightly Included 1, 2. Very minor inclusions that are difficult to identify under 10x magnification exist. These inclusions are not visible to the naked eye and are called “eye clean” by gemologists. Rare and valuable, these diamonds are less than 10% of the world’s diamond supply.

 

Polish & Symmetry+

Polish is an element of diamond finish and the smoothness of its outside surface.

Why is polish important?

  • Polish refers to the quality of the diamond's surface and includes such features as nicks, polish lines and abrasions.
  • Low polish grades such as Fair or Poor can affect the diamond’s sparkle and ability to absorb and reflect light. High grades, such as Excellent, Very Good, and Good, can bring out the reflective beauty of a diamond.

 

Which polish is for me?

  • Excellent polish diamonds carry a premium while Very Good and Good grades can be equally beautiful when evaluated by the unaided eye. Therefore, Very Good and Good grade diamonds can be more budget friendly.
  • GIA grades polish and symmetry as: Excellent (EX), Very Good (VG), Good (G).

 

Symmetry is the arrangement, size, and shaping of diamond facets.

 

Why is Symmetry Important?

  • Symmetry grades refer to how carefully and cleanly diamond facets have been cut in relation to each other. Low symmetry grades can have a negative affect on a diamond’s sparkle and its ability to hide inclusions. Low symmetry High symmetry grades are Excellent, Very Good, and Good.
  • A diamond with poor symmetry may misdirect light that travels into the diamond, sending it off at slightly wrong angles, and thereby reducing the diamond's brilliance.
  • Examples of symmetry imperfections: off center culet, misshapen facets, off center table, faceting that is not properly pointed, crown and pavilion misalignment, table and girdle not parallel.

 

Which Symmetry is right for me?

  • Symmetry can add value to a diamond. Excellent symmetry grades carry a premium while Very Good and Good grades can have little to no visual effect when evaluated by the unaided eye. Therefore, Very Good and Good grade diamonds can be more budget friendly.
  • Despite its modest impact on appearance, symmetry has a significant impact on price; a diamond with Excellent Symmetry and Polish may be priced 10% higher than a diamond with Good Symmetry and Polish. This premium has more to do with consumer's perceived value of "excellent" grades, than the actual effect on a diamond's appearance.

 

Fluorescence+

What is it?

The diamond’s tendency to emit a soft blue glow under Ultraviolet light.The fluorescence of a diamond is defined by its intensity as either None, Faint, Medium, Strong, or Very Strong.the visible effects of Faint to Medium fluorescence are perceptible only to a gemologist using a special UV light source.

None Fluorescence Diamond
Faint Fluorescence Diamond
Medium Fluorescence Diamond
StrongFluorescence Diamond

Why is Fluorescence important?

  • While fluorescence may have a stigma associated with it, it is not necessarily a bad thing. Fluorescent diamonds can often be less expensive. Generally, when diamonds have None or Faint Fluorescence, the appearance and quality of the diamond are unaffected and therefore so is the price. Approximately 30% of the world’s diamonds have Fluorescence in them.
  • The most common color of fluorescence is blue but other colors are possible too, i.e. yellow, white, greenish yellow, green and pink. Ultimately, this fluorescent color is determined by the chemical composition and make-up of the diamond’s lattice structure during its formation process.

Which Fluorescence is right for me?

  • In higher colors, such as D, E, and F, Four Mine does not recommend Medium or Strong Blue Fluorescence because it can make the diamond appear grayish or murky and brilliance can be negatively affected.
  • In lower colors, such as K, L, and M, higher fluorescence grades such as Medium or Strong Blue can actually improve the appearance of color. Fluorescence tends to make lower colored diamonds look whiter.

 

Certification+

A diamond certificate is a document describing the most important quality features of a particular stone.The certificate is issued in the form of a report and includes the stone’s characteristics (4 C’s, exact carat and diamond measurements) that have been measured using machines and evaluated by trained gemologists that help determine the diamond’s value. Different labs use their own grading report system. Most reputable one is GIA - Gemological Institute of America.

Certified VS. None certified Diamonds

  • The document will inform you what exactly you are buying and help you to avoid overpaying for a stone that should be priced lower because of its quality.
  • Recommended to always buy diamonds with a reputable labs certificate to check claims from a vendor.
  • To provide third-party verification of quality.
  • some diamonds have inscriptions in the girdle in the form of numbers and the lab that graded the diamond.
  • Certified diamond have documents that determine the stones key quality characteristics .

 

Appraisal

  • Document that puts a monetary value on a diamond (or a piece of jewelry); it is often used to determine how much you should pay for the insurance of the stone.

Gemstones+

Ruby+

About

Ruby is one of the rarest and hardest gemstone, only second to diamonds. Rubies are so rare and expensive, in fact, that manufacturers prefer to cut them into Oval and Cushion shapes, so that ruby rough isn’t wasted. Round shaped rubies are also popular, but tend to be more expensive because more rough is required.

To many, rubies represent integrity, devotion, happiness, healing, courage, romance, generosity, inspiration, and prosperity. Ruby is July’s birthstone. Rubies represent romance and true devotion, which makes them an excellent choice for engagement rings and bridal jewelry.

Color

Four Mine offers the rarest rubies, which have a pure vivid red colored hue. Typically, rubies have a pink or purple color. Four Mine only offers the highest AAA quality rubies that have an intense color and not an opaque look. Whitish and light red opaque colors tend to be a result of inclusions and poorer quality. The grading scale for gemstones is AAA, AA, A, B in their respective quality order.

The higher the red saturation in a ruby, the rarer and more expensive. Four Mine only carries the reliable and rare quality rubies. Rubies can be too deep in color as well, which makes them look dark or black-ish. This is undesirable and reduces ruby value and visual appeal.

Clarity

Gemstone clarity refers to the visible imperfections found naturally within the gemstone. These imperfection come in a variety of sizes, shapes and forms. They are often more visible than in diamonds because of the lack of reflective qualities in rubies. Ruby clarity is graded without magnification by holding the ruby face up about one foot away from the eyes. The ruby is rocked and tilted slowly back and forth to identify color and clarity.

Ruby value is reduced when clarity inclusions are noticeable or obvious and make it difficult to see into the gemstone’s center. Four Mine uses only the top 1% of all gemstone quality rubies so these imperfections are not noticeably visible.

Origin

Four Mine carefully selects suppliers and manufacturers of Ruby to ensure ethical sourcing and origin. Our suppliers go through strict practices, which include certification and authentication of origin in order to verify ethical mining practices and the conflict-free nature of the rubies.

Our rubies come from a variety of locations globally. Because we use only the highest quality rubies, we source much of our inventory from Myanmar (Burma). The highest quality (color and clarity) rubies can be found naturally in Myanmar. Rubies also originate from Madagascar, Thailand, Tanzania and Mozambique. ORigin can often be identified by the tints and hues or color and color undertones.

Treatments

All Four Mine rubies are natural and authentic. Our gemstones are carefully selected and undergo rigorous gemologist inspection by in-house gemologists certified by GIA’s educational programs. We do not set and offer synthetic rubies and non natural gemstones. Typically, the vast majority of gemstones undergo minor treatments to improve their visual appeal. These methods have been used by jewelers for hundreds of years. Gemstones without any kind of treatment are extremely rare and extravagant in price, like natural diamonds, for example.

These treatment include:

Heat: Applying high heat can often enhance the color or clarity of a gemstone. This technique is employed by ruby cutters when polishing and finishing. It is a generally accepted practice by the American Gem trade Association. Heat treatments are permanent and do not adversely affect the structural integrity of your ruby.

Filling: Gemstone cavities can sometimes be filled with oil, wax, resin or glass to improve the visual appearance and structural integrity of the ruby. This is an age old process that have been applied by jewelers for centuries. It is a great way to preserve the value of the gemstone while improving its aesthetic appeal. Four Mine rubies undergo as few treatments as possible in order to offer the most authentic gemstone experience.

Emerald+

About

Emeralds have a beautiful, intoxicating green hue and tone, which is almost impossible to replicate in any other gemstone. Emeralds can be identified by their deep, rich green color. They often have a bluish undertone, unlike other green gemstones which have a yellowish undertone.

Four Mine sources the highest quality emeralds sourced from the top emerald miners in the world. This is particularly important because unlike diamonds, emeralds have no standardized grading practices.There are many different hues, saturation and tones in emeralds that it is nearly impossible to create a standard grading system. Therefore, Four Mine gemologists inspect every emerald and certify their quality independently and reliably.

Color

The highest quality emerald have an intense and vivid green color and even saturation/distribution of color. Four Mine only uses AAA quality emeralds that meet these standards. Deep, Medium and Soft green colors have less desirability and value. The intense and vivid colors are more rare and make your jewelry light up and shine. They represent less than the top 1% of all gemstone quality emeralds available. The grading scale for gemstones is AAA, AA, A, B in their respective quality order.

Clarity

High purity emerald are extremely rare. Emeralds almost always have tiny inclusions, which make each emerald so unique. The inclusions define the emerald and form patterns. Most commonly, you’ll see tiny inclusions known as cavities, feathers, or color zoning. Clarity is graded without magnification, holding the emerald about 12 inches away from eye level. The emerald is slowly tilted back and forth to evaluate the quality. Because grading is not standardized, Four Mine gemologists independently verify and grade each emerald. We certify their quality and choose only the finest quality emeralds with minimal inclusions and the best available purity.

Origin

Four Mine emeralds are mined using the strictest environmental safety and ethical practices to ensure community building. We take a community first approach and reject many emerald suppliers who cannot provide origin reports and validity of rough sourcing.

Most emeralds are mined from Columbia. Colombian emeralds have fine quality and provide greater supply. Emeralds can also be sourced from Zambia and Brazil. Colombian emeralds have the best gemstone quality to make your jewelry light up and shine. Each origin can offer higher and lower quality emeralds. Therefore, it is critical to source emeralds that come from best practices so you can ensure not only the quality of the emerald, but its mining methods and standards.

Treatments

All Four Mine emeralds are natural with certified authenticity. Our gemstones are carefully selected and undergo rigorous gemologist inspection by in-house gemologists certified by GIA’s educational programs. We do not set and offer synthetic emeralds or simulants. Typically, the vast majority of gemstones undergo minor treatments to improve their visual appeal. These methods have been used by jewelers for hundreds of years. Gemstones without any kind of treatment are extremely rare and extravagant in price, like natural diamonds, for example. These treatment include:

Heat: Applying high heat can often enhance the color or clarity of an emerald. This technique is employed by emerald cutters when polishing and finishing. It is a generally accepted practice by the American Gem trade Association. Heat treatments are permanent and do not adversely affect the structural integrity of your emerald.

Filling: Gemstone cavities can sometimes be filled with oil, wax, resin or glass to improve the visual appearance and structural integrity of the emerald. This is an age old process that have been applied by jewelers for centuries. It is a great way to preserve the value of the gemstone while improving its aesthetic appeal. Four Mine emeralds undergo as few treatments as possible in order to offer the most authentic gemstone experience.

Sapphire+

About

Four Mine sapphires have a beautiful, glowing blue hue and saturation. While sapphires come in many colors, blue sapphires are the most valuable and richest in color. Sapphire’s blue can be vivid and saturated, like it’s lit from within. They are extremely durable and often contain delicate intersecting lines of rutile that gemologists call silk.

We value ethical sourcing above all else. Our sapphires are mined and sourced fair trade and with environmentally responsible practices. All sapphires (cutting and mining) collow strict labor, environmental and ethical principles.

Color

Sapphires of the highest quality have clean, even saturation of vivid blue color. Four Mine gemologists examine every sapphire to ensure the quality of color and clarity in the sapphires. Color is determined by examining hue, tone, and saturation.

Four Mine uses only violet-blue to deep blue colored sapphires. These sapphires have evenness in color. We avoid light blue colors which show whiteness in the sapphire or lack of color. Our sapphires are selected based on the purity of color so as to avoid gray or brown undertones.

Clarity

Sapphires are formed and mined in mineral heavy environments, which can like small elements within the sapphire. These may present themselves as tiny impurities in the sapphire. Often, these are tiny crystals, feathers or needles or inclusions. Because sapphires have such a deep, rich blue hue and saturation, many of these are unnoticeable. Sapphires without noticeable impurities offer an excellent value and represent the top 1% of gemstone quality sapphires. Four Mine only carries this quality of sapphire. Sapphires are graded by gemologists without magnification and slowly tilted back and forth during examination.

Origin

Sapphires were some of the very first cut and discovered gemstones. They’ve always been a prized gemstone because of their mesmerizing color. While sapphires come from a variety of locations geographically, the vast majority of high quality blue sapphires come from Ceylon (Sri Lanka).

Four Mine sources sapphires carefully with special attention to mining practices local community support. Sapphires have been a huge economic support to local communities in Sri Lanka for generations. Traditional mining practices are stilled employed to this date, of course with higher safety and technological advances. Four Mine supports suppliers in these local environments with local buyers who supply sapphires direct from the source.

Treatments

All Four Mine sapphires are natural. Our gemstones are carefully selected and undergo rigorous gemologist inspection by in-house gemologists certified by GIA’s educational programs. We do not set and offer synthetic sapphires. Typically, the vast majority of gemstones undergo minor treatments to improve their visual appeal. These methods have been used by jewelers for hundreds of years. Gemstones without any kind of treatment are extremely rare and extravagant in price, like natural diamonds, for example. These treatment include:

Heat: Applying high heat can often enhance the color or clarity of an sapphire. This technique is employed by sapphire cutters when polishing and finishing. It is a generally accepted practice by the American Gem trade Association. Heat treatments are permanent and do not adversely affect the structural integrity of your sapphire.

Irradiation: Causes permanent color change at the molecular level. This can cause sapphires to be colors other than what was mined from their origin. Four Mine does not use irradiated sapphires.

How to Buy Engagement Rings+

There is no better way to eternalize your love than an engagement ring. Traditionally, engagement rings are set with diamonds, which are the hardest material on earth. They are durable, everlasting and timeless. Their distinctive shapes, eye catching sparkle and rarity make them the most preferred choice of gemstone.

Setting Your Budget

The first step in the engagement ring process is to determine your budget. Four Mine carries rings and diamonds that fit all budgets. Pick a budget that you are comfortable with. Our aim is to help you find the optimal ring and diamond for your desired price point.

Selecting A Shape

The second step toward selecting the perfect diamond is choosing the right shape. Four Mine offers the 10 most popular shapes. Each shape has a unique style and a signature beauty. Round diamonds are traditional, possess maximum sparkle and are by far the most popular shape. The majority of all engagement rings have a round center stone. Other fancy shapes offer also offer distinctive visual appeal and can be set to create striking engagement rings. Choosing the right shape is critical as the center stone is the focal point of your engagement ring. Fancy shapes (shapes other than round) are generally less expensive than rounds. After round, the most popular and trendy shapes are cushion and princess diamonds.

Choosing A Diamonds

Finally, the 4C’s of diamonds (carat, cut, color & clarity) must be evaluated. The 4C’s tie together your budget and shape. Think of the 4C’s as a scale with carat on one side and cut, color and clarity on the other. Generally, if you increase one side, you must decrease the other to accommodate your budget.

It’s best to generally start with size. Once you have a size in mind, you can see the possibility of cut, color and clarity that exist within your desired size range, shape and budget. Size is the most visual “C” as an untrained eye can notice a difference between a 1ct and 2ct diamond.

Diamond Quality

The second most important “C” is cut, which directly correlates to diamond sparkle. The finer the cut, the better the sparkle. Select a higher cut grade for rounds (Excellent or Very Good); for fancy shapes selecting a Good cut is perfectly acceptable and will still yield a beautiful diamond. We guarantee that all Four Mine diamonds are of high quality and possess scintillating sparkle.

Finally, consider color and clarity. Color is generally only noticeable in lower colors (K or below). Clarity is rarely visible to the naked eye, except for I1 diamonds and lower. Four Mine doesn’t carry colors lower than L and clarity grade lowers than I1 to ensure your diamond quality is high regardless of your selection. All our diamonds come with an independent grading certificate that verifies your diamond quality.

Choose the Right Size

Use our size guide to determine her ring size accurately. You can also look for a ring that she wears on her ring finger and determine her size with that. If you get the size perfect the first time, your work is done. If not, don’t worry! Four Mine offers free resizing for up to 30 days. We understand that this is not an exact process, and factors beyond your control can influence the determination of ring size. Resizing is quite common, so don’t feel like you’ve made a mistake.

Fitting

Rings are meant to be worn comfortably – not too tight, not too loose. As a good rule, the ring should be loose enough to pull over your knuckle with minimal effort. Remember that fingers tend to swell a bit during the summer, so keep that in mind when finding the perfect fit.

Proposing

Your proposal is one of the biggest moments in your life. Don’t be nervous- just be well prepared and everything will go smoothly. Remember the proposal is all about celebrating your relationship and making her happy. Keep this in mind as you decide the venue, style and what you’re planning to say. Remember to make it heartfelt and she’ll be sure to say yes. READ MORE

Selecting a Band+

Budgeting & Timing

Choosing the ideal wedding band that represents your union is a key part of wedding planning. The biggest pricing factors in bands are metal weight and total diamond carat weight. Four Mine offers a wide range of options and matching bands that are sure to be the right fit. Men may prefer alternative metals such as palladium as they are more budget friendly. For women, a band matching their engagement ring is ideal. Consider if bands are meant to be worn alone or with a band to determine sizing of stones and design.

Wedding bands should be purchased approximately 2 months in advance of the wedding. This offers you enough time to get the perfect band and ensure that the sizing is correct before your big day. We are happy to suggest styles that will match well with your engagement rings.

Wedding Band Style+

Four Mine wedding bands come in a variety of classic and contemporary styles. We have matching women’s bands for all our engagement rings. Choose a style accentuated with diamonds for sparkling appeal or a metal band for a classic commemoration of your bond.

Metal Bands - Women

Sleek and simple, metal bands for women can be worn with or without your engagement ring. We suggest a band that is the same metal as your engagement ring for maximum appeal. Yellow gold is classic, white gold is universally appealing and rose gold is a striking and unique look. Platinum offers a bit of extra durability and shine.

Diamond Bands - Women

Diamond bands are a beautiful balance between metal and diamond. They range from simple accentuation to sparkle nearly all around the band. This is a great option for those looking for both value and style in their wedding band. These bands can be plain or be curved so that they can be worn comfortably with the engagement ring.

Eternity Bands - Women

Eternity bands have the maximum sparkle as they have diamonds all around the band. They represent eternal love. Full and dazzling, these bands look beautiful worn with or without the matching engagement ring. Eternity rings tend to be pricier than diamond bands.

Men’s Bands

For men, we have styles ranging from simple and classic to unique and bold. Finishing and edging are an important component of the wedding band. Whether you prefer knife-edge, flat, domed or any other style, we've got variety in all finishes. For subtle style, try our popular satin finish bands.

Metal bands are most common for men. Yellow gold is traditional, while white gold is contemporary. Alternatives include platinum and palladium, which are very durable. Our metal finishing options add a unique style element to the classic band. Mixing metal finishes can give you band a unique look.

For men who prefer bands with more stylistic elements, we carry a wide range accentuated with round and princess diamonds. Diamonds on men's bands are very trendy and in fashion. They add an extra element of design and sophistication.
