Chatham

Our lab-grown gemstones and diamonds are grown just like you would culture a pearl. Natural ingredients are placed in an environment created to duplicate nature. Once the required combination of chemical and environmental factors is created, gemstone crystals grow over the course of about a year (the exact length of time depends on the variety). As a result, the crystals we grow have physical, chemical, and optical properties that are identical to those found in nature.

Unless you’re a certified gemologist with a powerful microscope, you won’t be able to tell the difference between Chatham-created and mined gemstones. Every gemological laboratory in the world has reference samples of Chatham Created Gemstones to aid in the separation. Chatham is at the forefront of full disclosure, contributing samples and updates whenever something new is released.
