About Chatham Online Online Jewelry Store

The Best Gems On Earth

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.

That famous Chatham quality is no accident: it’s the result of continuous technical refinement over our 75-year history. It starts with carefully controlling the gem crystal growth process but it doesn’t stop there. Our master gemstone cutters sacrifice 80% of the rough crystals to select only the best color and clarity. Then they carefully orient the rough gem, cutting to perfect proportions and polishing each facet by hand until every Chatham gemstone dances with brilliance.

For our award-winning jewelry collection, our master cutters have created exclusive new gem cuts you won’t see anywhere else. The romantic Flame Cut, curvy Onion Cut, elegant Elongated Pear, Oval, and Baguette cuts, and Checkerboard Antique Cushion and Barrel cuts add a fresh new look to our collections.

And our jewelry designs are just as innovative, with fluid lines of diamonds adding just the right brilliant accent to the technicolor brilliance of our gems.

At every step, our goal is the same: to create high quality jewelry that perfectly expresses your unique and colorful style. And you can feel good about the fact that our gems are better for the environment and our company is committed to social responsibility.

Since you’ll love wearing your Chatham jewelry every day, it’s also good to know you can enjoy our gems without worry, secure that they have the Chatham lifetime warranty.
