Natural vs. Lab Created Sapphire

Sapphires are very precious and desirable gemstones which are greatly appreciated by jewelry lovers. The reason is that sapphires have very attractive colors and are quite hard and durable. However, in as much as sapphires are natural gemstones, some are equally synthetic since they are lab-created. Many factors are taken into consideration when choosing between man-made sapphire and natural sapphires, but that’s a topic on its own. Let’s focus on the differences in the natural vs synthetically created sapphires.


Naturally vs Synthetic Gemstones

Many people confuse the word “synthetic” with “fake.” However, in many cases, this is an inaccurate assumption. When used in reference to “Synthetic” typically refers to something in nature that is developed, component for component, in a controlled lab environment. Such is the case with gemstones.

Sapphires, for example, are made from corundum, both in nature, from which they’re mined, and in labs, where they are harvested once the predetermined development period is over. Because no synthetic material is used to replace the corundum used to create sapphires, they are indistinguishable from one another by hardness and visual characteristics alone. To find the differences between the two types of sapphires, one must look more closely at the methods of formation and the environments in which both stones are developed.


Origin of Natural Sapphires

Sapphires, along with just about any of the harder gemstones (diamond, mossanite, etc.) aren’t just used for jewelry. They also have many industrial uses, from windows to lenses on a variety of devices and tools. The first such use of sapphires occurred over three centuries ago, when industrial grade sapphires were used as bearings for time pieces such as watches and clocks of that time period.

Various sapphires have origin stories that differ from one another. Original blue sapphires were among the first sapphires discovered decades ago, in places like Kenya, Ceylon, Australia and Vietnam. Other shades of sapphires, such as green, pink, purple, and the ever-popular multi-colored (parti) sapphires, have been discovered in more recent decades, in mines in or near the same regions as traditional blue sapphires.

One interesting note about the origins of natural sapphires is that, depending on the region from which they originate, or how “old” a particular fancy (different colored) sapphire may be, it can have a bigger impact on its market price than its official grade and rating from the GIA, or other expert gemological facility or organization. Natural sapphires of all colors that are rated as gemstone quality and marketed as such are rare enough. Sapphires from certain regions or during certain time periods, such as those from Burma, when it was still known as Myanmar, are more valuable than some mined, for example, in Australia more recently, or in larger quantity, regardless of flaws or the overall quality of the sapphires.


Origin of Synthetic Sapphires

The creation of synthetic sapphires followed shortly after the discovery of synthetic forms of corundum and the introduction of synthetic rubies in the late 1800’s. Both rubies and sapphires form from varieties of corundum, which is why there are no true red sapphires (although shades of pink sapphires exist, and are quite rare and valuable).

Since their first uses in the industrial market, synthetic sapphires have been created in various gem labs as a less expensive and more easily duplicated alternative to naturally formed sapphires.

Price Difference Between Natural and Synthetic Sapphires

The prices of different gemstones vary, depending on factors including the color hue and/or saturation and purity of the gem, clarity, facet shape and quality, and number (or lack) of inclusions, or flaws, in the stone. A gem’s value may, as we mentioned earlier, be decided entirely, or in part, based on where, how, and when it was mined.

Depending on their size, original blue colored loose natural sapphires of average to higher quality can reach upwards of $30 per carat. The best quality and highest rated sapphires could cost around $50 or more per carat. Their synthetic counterparts start at an average of about $8-$10 less expensive per carat than the natural sapphires. However, in some cases, the conditions in which the stones were synthesized are so like the natural conditions for “real” sapphire formation that they produce a quality of gemstone almost identical to real, or natural, sapphires. These synthetic gems could fall into a price range almost equal to the natural sapphires of the same or similar quality.

Note that these are often not the final prices for gemstones on the jewelry market. Their parings with other gemstones, jewelry settings, cuts, etc. will ultimately affect the sapphire’s retail price.

If you consider buying a real and authentic stone for its value and properties, then it is very essential to deal with a well-known, reputable, and honest dealer that you can trust. This is because the differences between the stones can only be differentiated by an expert or the buyer would face the risk of getting less than what you really require.

Ways to Tell the Difference Between Natural and Synthetic Sapphires

While research and discussions with gem experts and jewelry retailers will help you understand the differences between natural and man-made sapphires, there is little visual or physical evidence that differentiates one from the other.

Some of the differences between natural sapphires and synthetic ones include:


  • Flawlessness - Natural sapphires always have inclusions (flaws) when mined from the earth that formed in the sapphire crystal as the gemstone developed. Synthetic sapphires, as with other lab-created gems, form without these inclusions, because the natural variables to which the natural sapphires were exposed do not exist inside the laboratory conditions.

  • Price tag

  • Location - in regions where no sapphire mines have been located, but sapphire prices are seemingly low.
