Jewelry accounts for about two-thirds of the gold used commercially each year. Gold jewelry can be various colors, depending on the metals used in the gold alloy. For example, white gold is a silver colored alloy of gold, copper, and such metals as nickel, palladium, silver, and zinc. In yellow gold, about equal amounts of copper and silver are mixed with a greater amount of gold, so that the alloy retains the color of pure gold.

In the United States, the metal in solid gold jewelry is mostly 10-karat to 21-karat gold. Gold-filled and gold-plated items consist of silver or another metal coated with gold. In gold-filled items, 5 percent or more of the object's weight comes from gold. Gold-plated items contain less gold.

LOOKS LIKE 10K TO 21KT IS SOLID GOLD!!!
