What is Karat Grade?

For gold, karat grade is used to express the proportion of gold in an alloy or the quality of a gold alloy. Fine gold (pure) is 24 karat. The proportions in other karat are listed in the table below.

All jewelry is required by law to be stamped so consumers will know the quality of gold used. Jewelry made in North America is typically marked with the karat grade (10K, 14K, etc.), and jewelry made in Italy is typically marked with the "fineness" such as (417, 583, etc.). So if your jewelry does not have a karat grade stamped on it, check for a 3-digit fineness number.
