Fineness

Fineness is a measure of a precious metal’s purity, and it’s based on parts per thousand. A metal that rates 1,000 is described as fine, or pure. This means it has virtually no impurities, and it’s not mixed with another metal. If a precious metal is 75 percent pure, its fineness is 750. A precious metal that’s stamped “950” is very nearly pure.

Technically, there’s no such thing as a fine precious metal. Every sample has at least some impurities or is deliberately blended with another metal or metals to form an alloy.

This item is marked to indicate its gold content. The “750” means that there are 750 parts per thousand of gold in the alloy.
