Gold

Gold is a sturdy and durable metal that will not corrode, tarnish or rust. These qualities have made gold a preferred choice for crafting jewelry. Gold is also a malleable metal when heated, meaning that jewelers can craft and shape it in myriad of ways. The purity of gold is measured in Karats with 24 Karat gold being the most pure. The word karat is derived from carob. Carobs were seeds used to measure the weight of gold in ancient times. In it’s purest form gold is a bright yellow in color. When being used for jewelry, gold is typically mixed with other metals to create an alloy for both strength and hue. This ensures that the gold will remain strong through the years. The more metals are mixed with gold, the lower the karat becomes. Four Mine crafts jewelry using 14 Karat and 18 Karat gold. These two variation are the most popular within the United States. Below is a breakdown of the different metal options and their components:

14kt White Gold

14k white gold is 58.3% pure gold with a mixture of palladium, zinc, copper, tin and manganese. For an added measure of security, 14k white gold jewelry is typically coated in a protective plating of rhodium. Rhodium is a shining white metal coating that’s very similar in appearance to platinum. It adds an extra lustrous shine to the jewelry and makes it more scratch resistant. The pricing of gold is determined by the purity. Therefore, 14k white gold is a less expensive alternative than 18k white gold and is chosen more commonly for jewelry purchases. If you would like to maximize on other elements like larger gems or more design elements, you can opt for 14k gold.

14kt white gold is a versatile metal and is a great choice when paired with any precious or semi-precious gemstone.

14k gold is a durable metal that can be worn daily. It will not rust or corrode and if crafted well should not break. However, over time, gold can become dull or dirty. Regular cleaning can ensure that the gold retains it’s original shine and luster. To clean your 14k gold jewelry at home, use a mixture of warm water and a non-abrasive, gentle soap. Gently clean the surface of the gold with a soft-bristled brush to reach corner and hard-to reach spaces. Be sure to reach inside and underneath prongs to remove dirt and grease that can accumulate there. Once cleaned, rinse the jewelry and wipe dry with a soft cloth.

Feel free to wear your gold jewelry on a regular basis. However, be sure to take of rings when doing anything that involves cleaning, heavy labor, gardening or anything involving chemicals or abrasive materials. Also be sure to remove jewelry when swimming or playing sports and exercising. We also recommend removing rings when applying lotions, wax, bleach or harsh soaps to your hands. These chemicals can damage the surface of the gold. Although jewelry is crafted to be durable, it can become damaged if worn without care.

When not wearing jewelry, be sure to place your jewelry in a safe place. Store each piece of jewelry separately in a cloth or plastic bag. This will prevent the jewelry from rubbing against one another and getting scratched.
