Traditionally gold is stamped with a karat purity value. A 24k stamp indicates that the metal is 100 percent gold. Any karat amount less than 24 is divided by 24 to determine the percent of purity. Therefore 12-karat gold is 50 percent pure, and 10-karat gold is 41.7 percent pure. In gold pieces that are less than 10 karats, a number indicating the actual purity percent is often used instead of a karat amount, as in the case of the "375" stamp.

    What causes white gold to turn yellow?

    A:

    White gold, especially in some jewelry pieces, may turn yellow over time when its rhodium plating gradually wears off. Rhodium plating is the preferred plating method used on most white gold rings because it is a pure white metal. This property of rhodium gives white gold jewelry a much whiter appearance and a more brilliant sheen.

    Why is gold used to make jewelry?

    A:

    Gold is used to make jewelry because of the attractiveness of its luster and because of its rarity. It also doesn't tarnish and doesn't react with air the way a metal like iron does. Gold is malleable, which means it can be beaten into very thin sheets. It's also ductile, which means it can be stretched out into thin wire as in the findings of earrings.
