Gold Mineral Properties - Geology

The most obvious physical property of gold is its color. It is one of just a few minerals whose names are used frequently in common language as the name of a color. The color is not altered by tarnish or the development of an oxidized surface. However, the color of gold varies with its composition. The color of gold is not constant.
