The Rarity of Unheated Burmese Sapphires
Burmese sapphires that maintain strong color saturation without thermal enhancement represent a vanishingly small share of the global gemstone market. Because heat treatment is standard industry practice to improve color and clarity artificially, completely unheated stones backed by a premier GIA report remain in steady demand among connoisseurs and international auction houses.
