Have you ever been confused by the terms white gold, green gold, and rose gold? All real gold is yellow, isn’t it? So how do other colors fit in? Are they imitations? Actually, they are all metal alloys; new metals that are created by combining two or more different metals.
Gold Alloys
Colored gold alloys are just as “real” as their golden colored counterparts. Pure gold is generally too soft to be used for jewelry, so other metals are nearly always added to it, no matter which color of gold is being prepped for jewelry making.
Gold Karat Markings
-24K gold is pure gold
-18k gold is 18 parts gold and 6 parts of another metal(s), making it 75% gold.
-14K gold contains 14 parts gold and 10 parts of another metal(s), making it 58.3% gold.
-12K gold contains 12 parts gold and 12 parts of another metal(s), making it 50% gold.
-10K gold contains 10 parts gold and 14 parts another metal(s), making it 41.7% gold. 10K gold is the minimum karat designation that can still be called a gold in the U.S.
White Gold
-Nickel can be mixed with gold to create a white(or gray) color. It can cause dermatitis in people who are sensitive to nickel.
-Palladium is another metal used to create white gold alloys. Related to platinum, it is more expensive than nickel, but it is less likely to cause allergic reactions than nickel.
Rose and Pink Gold
-Copper is added to make gold-colored alloys, but additional copper creates pink and rose tones, the more copper, the deeper the effect.
Green Gold
Greenish shades are created by adding silver to gold.
Making alloys isn’t as simple as it might sound. Before they make an alloy, metallurgists have to consider how the metals will react with each other. Adding too much of one metal or another can make the mixture brittle, too hard, or difficult to work with. Some ingredients could make the mix too soft.
Metallurgists fine-tune their recipes to produce combinations that are attractive, durable and can be successfully worked into pieces of jewelry.
