Up to 99 % of all Sapphires are heat treated; Sapphires have been treated for centuries by heat to enhance their color and clarity. The early forms of heat treatment were rudimentary and highly risky involving heat and blow pipes the results were unpredictable and often shattering. Today we have computer controlled ovens that heat the sapphire anywhere from 700 degrees to super-heated and treated 1950 degrees for a period of hours to weeks altering the atomic structure to improve color and clarity, often adding filling material such as colored glass to heal and fill cracks or fissures.
