What Is 1/20 14k As It Pertains to Jewelry?

A stamp of 1/20 14K on jewelry indicates that the piece is gold-filled. The 1/20 means that there is one part gold to every 20 parts of other materials. The 14K on the stamp notes that the gold used is 14-carat gold.

Gold-filled jewelry is commonly known as costume jewelry. It typically is of little financial value, unlike items made of solid gold. Jewelry that is marked above 1/20 is considered gold-plated rather than gold-filled because the gold content is higher in the piece. Typically there are 5 grams of gold in a 1/20 gold-filled piece, or 5 percent real gold content.
