Created Gems & Diamonds
Chatham grows gorgeous gem crystals, cuts them precisely to sparkle with brilliance, and crafts unique jewelry designs to showcase their beauty. We are one of the few vertically integrated brands in the jewelry industry, which allows us to offer you exceptional quality and value. That’s why more people choose Chatham than any other lab-grown gem.
Chatham-created gems are in the collection of the Smithsonian Institution and the collection of the Gemological Institute of America. We’re proud of our rich history but even more proud that our tradition of innovation continues today.
