The "King Of Gems", Ruby is one of the world's oldest and most revered gemstones. It is also one of the rarest gems and Rubies with hardly any inclusions are so rare, that large stones of good color can be auctioned for higher prices than diamonds. The mineral Chromium is responsible for its vibrant color. 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 Ruby was first developed in 1958. An accomplishment of brilliance, the art of producing these gems remains within the Chatham family only.
