Are Chatham Created Gemstones real? Or are they artificial?
Chatham 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.
Are there cost savings with lab-grown gemstones?
The price difference between Chatham and mined gemstones of similar quality can be dramatic. The difference varies from 30% – 80% depending on the size, shape and quality of the gemstone. The price difference increases substantially as the weight and quality of the gemstone rises.

This range of exclusive pieces have been designed by our in house master goldsmith Mike Taylor using Chatham lab grown gemstones.
How are Chatham lab grown gemstones made?
Every Chatham lab grown gemstone gets its start with an earth-mined crystal slice placed inside a crucible chamber. The chamber is then filled with a liquid containing the ingredients needed to feed crystal growth. The chamber is then sealed and the crystals are left to grow for six months to a year!
Are lab grown gemstones ethical?
No products have zero environmental impact. But it’s true that the production of the Chatham lab-grown gemstones does not require moving large amounts of earth like mining. Crystal growers do use energy and chemicals derived from the earth but the carbon footprint of crystal growth is a small fraction of natural gemstone mining.
