The composition and physical properties of a created sapphire are exactly the same as a natural stone. A sapphire, at its chemical basis, is aluminum oxide, Al2O3 -- 52.9 percent aluminum and 47.1 percent oxygen. Also referred to as "synthetic" and "simulant," lab-grown jewelry-quality sapphires are made primarily via two methods. The first, the Verneuil flame-fusion process, has its roots in 1902. Each crystal is formed individually, using a blowtorch. Aluminum or titanium oxides, in their purest form, are melted in a small furnace. To produce the desired color, other oxides are added. The crystal, which is called a boule, is formed on a rotating clay peg as it is brought out of the furnace. The second method is called the Czochralski pulled-growth method, which was developed around 1917.A Beautiful Blue Sapphire 38.77 Ct. 21.8x18.3x11 This is a real Sapphire but it was not mined, it was Lab grownthe ring is not included, If you do not love it I will refund in full !!!
