Eco-Friendly Diamonds & Gemstones
For green-minded and budget savvy consumers, we're proud to offer you eco-friendly Chatham-created gems for your gorgeous custom ring. Choose from a variety of lab-grown synthetic gemstones including rubies, sapphires, emeralds, alexandrites and diamonds.

Chatham-created gemstones are real. Chatham doesn't make gemstones, it creates the environment in which gems can grow naturally. Chatham gemstones and diamonds are cultured just as many pearls; natural components are placed in an environment created to duplicate nature's. Once the required combination of chemical and environmental factors is created, the crystals grow over time, the exact length of time depends on the gemstone. As a result, quality diamonds and gemstones are developed with identical physical, chemical, and optical properties to those found in nature. The good news is, they weren't dug out of the ground.

Unless you're a professionally trained gemologist with a powerful microscope, you won't be able to tell the difference between created and mined gemstones. Every gemological laboratory in the world has reference samples of Chatham gemstones to aid in the separation. Chatham is at the forefront of full disclosure, contributing samples and updates whenever something new is released. Diminish your carbon footprint by featuring a Chatham-created center stone in your custom ring.

Top Color & Quality Backed With A Warranty
Chatham stones boast top quality and color. Under advanced laboratory conditions our crystal growth is more predictable and consistent, yielding a superior end product. We strive to offer only best qualities and colors found in nature. Lower qualities are not released for sale.

Trust, integrity, and value are at the heart of Chatham. For your peace of mind, we provide a lifetime warranty on Chatham stones with your Certificate of Authenticity. Chatham will gladly repair or replace your gemstone at no charge if it should chip or break under ordinary circumstances excluding labor-related damage and normal wear and tear. If a replacement gem is needed, consideration will be taken to honor the original size and weight of the gem purchased.
