Fine Gold What is Considered Fine Gold? JM Bullion

Most commonly, fine gold is 999. This is the gold most commonly referred to as 24 karat gold, although technically 24 karat gold is 100% pure. However, as this is difficult to achieve outside of a lab environment, 999 gold is generally considered close enough. Gold manufacturers are legally allowed a half-karat tolerance in making gold products.

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
