Chatham Created Gems
Special-Offer and Custom Cut Lab-Grown Gems
Need a unique lab-grown gemstone for your special jewelry masterpiece? We can custom cut any of our regular Chatham-Created Gems in just about any shape and size. We also offer Chatham amethysts, white sapphires and Paraiba spinels as custom cut stones. Likewise, there is a very limited inventory of our seafoam garnets left as well.
Seafoam garnets were created as part of a Chatham materials research project to grow a synthetic Paraiba look-alike. While the experiment was successful in creating these fabulous gemstones, it wasn’t kind to the machines used to do so. So these beautiful Chatham gemstones are truly a once-in-a lifetime opportunity. Inventory is slim and once the supply of these stones runs out, they’re gone for good.
Oliver and Amie (right) wanted something special and unique for her engagement ring, so they bought one of our Chatham seafoam garnets to be set into one of our amazing engagement rings, shown left. They couldn’t be happier with their ring.
The good news is, Chatham found another way to make Paraiba look-alikes! Paraiba spinels were successfully developed recently to mimic the gorgeous color of Paraiba tourmalines. Chatham Paraiba spinels, rating 8 on the Moh’s scale of hardness, are a more durable, less expensive alternative to natural Paraiba tourmalines. Natural Paraiba tourmalines rate 7 on the Moh’s scale of hardness and their rarity makes them extremely pricey. Chatham gem-quality Paraiba spinels cost a fraction of natural Paraibas for the same color and clarity. We offer Chatham Paraiba spinels as custom cut stone in two different hues.
Chatham amethysts are real amethysts, grown under controlled conditions. So their color and quality are top-notch! Chatham amethysts rival the finest natural amethysts on the market with their rich purple color and gem-quality clarity. The pear shaped amethyst shown in the rose gold ring to the left shows the beautiful color of Chatham amethysts.

Our Work In Madagascar
Changing lives for children and their families
We get our hands dirty!
In 2014 Michelle went to Madagascar to learn about the geology and mineralogy of the country. She was excited to visit some of the mining localities she learned about in her studies to be a Graduate Gemologist. However, it wasn't the sparkly colorful gems that caught her eye. Rather, it was the children...the little gems of Madagascar. Michelle founded www.GemsOfMadagascar.org in 2015. She visits Madagascar for about two months each year doing humanitarian projects, including clean water, sanitation, education and hygiene.
