Chatham Alexandrite Ring-CR7258WAL
Emerald by day. Ruby by night. Alexandrites are a rare variety of the mineral chrysoberyl that changes color from bluish-green in daylight to purplish-red in incandescent light. Chatham is thrilled to make this rare gem available for people who have always wanted one at a more affordable price over mined.
After creating emeralds in 1938, laboratory grown rubies, alexandrites, and a variety of sapphires all came to fruition over many decades of research in the hands of Carroll Chatham.
By duplicating the conditions deep within the Earth – the temperature, the pressure, and the chemical makeup, his laboratory succeeded in growing gemstones over a course of a year’s time. These gemstones possess the same physical, optical, and chemical properties as their mined counterparts.
Today, Chatham is still recognized as the leader of laboratory-grown gemstone and diamond jewelry revered for its superior quality and everyday elegance. The company's unbeatable Lifetime Warranty and Certificate of Authenticity assure reliability and long-term value.
