Chatham Lab Created Gemstones 




6mm, 1.0 Carat Chatham® Emerald Lab Created Gemstone

Select one of our Chatham Lab Created Gemstones and your ring will arrive with a perfectly set stone.

Chatham lab-grown gemstones are cultured. 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 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. 

They are created unfer laboratory conditions, computer controled temperatures. Foreign materials found in the earth are also eliminated from their starting chemicals. This makes the crystals growth more predictable and consistent.
