Chatham Gemstones - From Humble Beginnings – The Unique Discovery of Lab Grown Chatham Gemstones
The renowned Chatham gemstone has its roots in a San Francisco garage occupied by a 12 year old chemistry buff in the 1920s. Carroll Chatham was always drawn to scientific experimentation and as a young boy he set up a lab in his parent’s garage, creating home-made smoke bombs and fireworks for fun. He later became interested in gemstones and replicated some of Henri Moisson’s 1890 failed diamond
creation experiments. After an explosion shook his entire neighborhood resulted from the immense pressure being used, Chatham turned his attention to Emeralds
as crystal formation requires less pressure. When he left home for college, his father serendipitously pulled the power plug on the science project which enabled Emeralds to form in the crucible. After three years of trying to understand exactly how the Emerald
crystals had grown, he realized that by duplicating the conditions deep within the Earth, with the proper temperatures, pressures and chemical solutions, that his laboratory was capable of actually growing gems. In 1938, after many years of research and determination, Carroll F. Chatham, a self-taught scientist in California, had finally discovered the secret of growing gems. A discovery so unique, it remains a carefully guarded family secret to this day.
Are Chatham Created Gemstones Real or Imitation?
Chatham Create gems are 100% real gemstones. Just as cultured pearls are formed in a controlled environment that replicates the natural process, so too Chatham gemstones created in a laboratory are just as real as naturally occurring gems. By precisely manipulating chemical and environmental factors with special computers, the crystals are left to grow of the course of about a year. These gemstones possess the same physical, chemical, spectral and optical qualities of mined gems at a fraction of the cost.
