Gold in its pure form (24k) is too soft to withstand abrasions caused from extensive daily wear, so it is alloyed with other metals to give it strength. This strength makes gold an excellent choice for a ring setting. Common gold alloys are silver, copper, nickel, and zinc.

Gold color is determined by the percentage of alloys that are included in the metal. When gold is alloyed with silver, copper, and zinc, the shade of color will vary. When gold is alloyed with nickel, copper, and zinc, it becomes white gold. Yellow gold and white gold have very similar strength and malleability. White gold looks very similar to platinum, but the two have very different properties and prices.

The purity of gold is measured in karats, which are expressed in 24ths. Thus, 24-karat gold is pure while 12-karat gold is 50 percent gold and 50 percent alloy.

Pricing
The price of gold jewelry is dependent upon the purity of the gold used or karat weight, as well as the design and construction of the piece of jewelry. When the karat weight or the gold percentage of the jewelry is high, the yellow color of gold is brighter, raising the value of the jewelry.

Taking care Of Gold
Gold won’t tarnish, rust, or corrode, and though it’s very strong, it is also the most malleable of all metals.
