Such minerals either contain the atoms of only one element or else are metal alloys. The native elements are divided into metallic, semimetallic, and nonmetallic subgroups. Metals tend to be dense and malleable substances which possess a characteristic metallic luster and conduct electricity well.

Gold itself does not corrode, but its primary alloys of silver or copper do so - forming very dark chemical compounds - under moist or wet conditions. When a person perspires, fats and fatty acids released can cause corrosion of 14-karat gold, especially when exposed to warmth and air.

The measure for the fineness of gold and gold alloy, expressed as a number, Out of 24 parts by weight, of parts of gold in the alloy, e.g. '24 carat' means pure gold, '14 carat' means 14/24ths gold in the alloy.

In order for gold to be usable for jewelry, it must be mixed with other metals to form an alloy which is stronger than gold in its pure form. So, 14K gold is 14/24 pure, or about 58.5% gold and 41.

To form rolled gold, a silver plate containing gold alloy was placed against copper or copper alloy. The two pieces were heated, typically by rolling, until the silver "sweated" off and the gold bonded chemically to the copper backing.

However, creating gold alloys has another benefit, in that, by choosing the alloying metals carefully, the gold can be imparted with another desirable color. For example, yellow gold is alloyed with an equal mixture of silver and copper, which maintains the yellow color of the gold.

Gold is typically melted down, alloyed with other metals for form jewelry, or bullion. Gold purity is expressed in terms of karat (kt) value, and is a fraction of 24ths. 24 karat gold is 24/24 gold and is pure gold. Gold having a hardness of 2.
