Sapphire is any gem-quality specimen of the aluminum oxide mineral corundum that is not red. While sapphires are often blue, they can be colorless or any other color. Colors are created by trace amounts of iron, copper, titanium, chromium, or magnesium. The chemical formula of sapphire is (α-Al2O3). Its crystal system is trigonal. Corundum is hard, around 9 on the Mohs scale. Citation
