What is Gold?
Native Gold is an element and a mineral. People highly prize it because of its attractive colour, rarity, resistance to tarnish, and many special properties unique to Gold. No other element has more uses than Gold. These factors help support a price of Gold that is higher than all but a few other metals.
Trace amounts of Gold are almost everywhere, but large deposits are in only a few locations. Although there are about twenty different gold minerals, all of them are pretty rare. Therefore, most Gold found in nature is in the form of the native metal.
Gold occurs in hydrothermal veins deposited by ascending solutions, disseminated particles through some sulfide deposits, and in placer deposits.
The most apparent physical property of Gold is its colour. It is one of just a few minerals whose names are used frequently in the common language as the name of a colour. The colour does not fade by tarnish or the development of an oxidized surface. However, the colour of Gold varies with its composition. The colour of Gold is not constant.
