Study on Coloration Mechanism and Enhancement of Low Quality Sapphires from Madagascar

Qiu Chengjun;Wang Yiqun;Huang Yuexia;Gemstone Testing Center, East China University of Science and Technology;  
Madagascar is now the most important origin of sapphire all over the world. Aiming to analyze the coloration mechanism with ultraviolet-visible absorption spectrum and X-ray fluorescence(XRF) and to explore the heat treatment process of low quality sapphires from Madagascar, the sapphire samples are treated at 1300 ℃~1600 ℃ for 12~20 h in the air, most of the samples become light ones with weaker Fe2+/Ti4+charge transfer, and some samples show fine color in blue with the decline of Fe3+and increase of Ti4+.
