How Is Gold Graded? BullionByPost

The term gold grade is commonly confused with gold purity, with the two meaning something quite different. Gold grade is a term used in gold mining, and should be used as a measure of the quality of gold ore – that is the raw material obtained from mining. Gold purity measures the amount of natural gold mixed with other metals in finished gold products or, more strictly, gold alloy products ...
