10K, 14K and 18K gold jewelry are most commonly used to manufacture gold jewelry and yet literally have less actual gold content. *10K gold may have the number “417” stamped on it. This indicates that the items are 41.7% gold with the remainder being other metals or alloys such as silver or nickel. *14K gold, may be stamped with “585” because the content of the metal is 58.5% gold. The majority of gold jewelry we see in our stores is 14K because it works perfectly for everything from rings and bracelets to chains and earrings. *18K Gold jewelry is very popular in Europe and South America. It has a deeper golden tone than 10K and 14K gold and may have a “750” stamp indicating it is 75% gold
