GoldThe metal has been known and highly valued from earliest times, not only because of its beauty and resistance to corrosion, but also because gold is easier to work than all other metals.

The unit used in weighing gold is the troy ounce; 1 troy ounce is equivalent to 31.1 grams.
The major portion of the gold produced is used in coinage and jewelry. For these purposes it is alloyed with other metals to give it the necessary hardness. The gold content in alloys is expressed in carats. Coinage gold is alloyed with copper or silver. Green gold used in jewelry contains copper and silver; white gold contains zinc and nickel, or platinum metals.
