After creating emeralds in 1938, laboratory grown rubies, alexandrites, blue sapphires, and orange sapphires all came to fruition over many decades of research in the hands of Carroll Chatham. A few years after his passing in 1983, his lifelong dream of diamond cultivation finally became a reality for his son, Tom.
Today, Chatham is still recognized as the leader of created gemstones. The company's unbeatable Lifetime Warranty and Certificate of Authenticity assure reliability and long-term value.
