10-karat gold is the minimum purity that can legally be sold as "gold" in the United States. It is 10 parts gold out of 24, or about 41.7% pure gold, with the remainder made up of harder alloy metals.
Because it is less than half gold, 10K has the lowest melt value of the common karats - but it is extremely common in class rings, chains, and everyday jewelry. Enter the weight to estimate value at the live spot price.
