Modern technology. Cutting edge design. Environmentally friendly products. Vibrant color. That’s Chatham. Our branded jewelry collection featuring lab-grown gems is as innovative as it is beautiful.
Like many a tech company, Chatham started in a garage in California. Carroll Chatham was the first in the world to grow emerald crystals from scratch. Today the company he founded 75 years ago is the world’s leading source of high quality laboratory-grown gems.
Chatham grows the best gem crystals on earth, 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 Institute 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.
