Gemstone + Diamond Suppliers
When I first got started as a jeweler, gemstone sources were often closely guarded — and for good reason. These relationships can take years to build, and unique stones are often what set a jeweler’s work apart. This list is meant to help connect you with gemstone dealers and lapidary artists you can trust, in a market that can otherwise feel overwhelming.
Every seller on this page is someone whose stones I’ve either seen firsthand or who comes highly recommended by the Metalsmith Society community.
