Over 80 years ago, Carroll Chatham introduced the world to laboratory grown emeralds. By duplicating the conditions deep within the earth, his laboratory succeeded in growing the finest gems over the course of a year’s time. A discovery so unique, it remains a carefully guarded corporate secret to this day. Chatham is now recognized worldwide as the industry leader in luxury laboratory grown gemstones and diamond jewelry.
