Chatham is still recognized as the leader of laboratory-grown gemstones. 
Every Chatham lab grown gemstone gets its start with an earth-mined crystal slice placed inside a crucible chamber. We fill the chamber with a liquid containing the ingredients needed to feed crystal growth. This “liquid” is only possible at 1100 degrees Celsius! Looking into the chamber is like looking into a volcano.
