Alexandrite dates back to the 1830's, this mystical gem was first discovered in th the Ural Mountains of Russia and got its name Alexandrite from the Czar Alexander II. In 1938, Carroll F. Chatham, a scientist from San Francisco after many years of research and great determination, discovered the technique of growing gems. His theory was that by, replicating the natural conditions deep within the earth, the appropriate temperatures, pressures and chemicals, he would be capable of growing a gem in his laboratory. Based on his theory, at a fraction of the cost of a mined gem, he could grow gemstones possessing the same physical, chemical, spectral and optical qualities of mined gems. Chatham Created Alexandrite was first developed in 1972. An accomplishment of brilliance, the art of producing these gems remains within the Chatham family only.
