Sapphire heat treating has been practiced worldwide for hundreds of years. Heat treating is a process of taking sapphires to high temperatures, and the high temperatures react with natural elements already present in the sapphires to enhance the stones' best color. Heat treating produces dramatic results by minimizing color zoning and improving the stone's saturation. For example, a blue sapphire can have green undertones, and heat treating would optimize the gem's color intensity and clarity by minimizing those undertones. While there is always some risk of fracture, all stones at Sapphire Gallery, in Philipsburg, Montana, are heat treated locally in a controlled atmosphere with optimal conditions for improving the quality and value of the stones.
Just wanted you to sincerely know how much I enjoyed my first visit to your gallery and am looking forward to many more. It just doesn't get any better than this. It is sapphire heaven! I know I must be patient for the next six weeks, but to tell you the truth, it won't be easy.Linda, Idaho
