| Gold jewelry never goes out of style, and for good reason, because gold is as wearer-friendly as it is beautiful. Pure gold doesn't react with other elements to create tarnish, the residue that accumulates on some metals before transferring to your skin as a stain. Sometimes people have allergy or staining problems with metals that are combined with gold, but the gold itself is rarely a problem...... | |||||||||||

Why Are Other Metals Mixed With Gold?You'll find examples of pure gold jewelry, but pure gold is soft and isn't practical for daily wear. Other metals are mixed with it to make it more durable (and to lower its cost). Adding other metals to the mix also allows metallurgists to change the color of gold. Palladium or nickel can be added to create white gold. Adding copper produces a rose or pink tint, while silver gives gold a greenish cast. When metals are added to the gold the result is an alloy, a blended mixture of the metals that you can think of as a very expensive cake batter. Solid gold is a term that can be used to describe an item that's at least 10K (in the US) gold all the way through. Even though it's a gold alloy--18K, 14K, or anything down to 10K--it can be called solid gold.. |
