All corundum gemstones are known under the name of sapphire with the only exception of the ruby red variant which is called ruby. But the name sapphire is very widespread, for blue precious stones, but this blue should not be understood as the color of the clear sky, but all shades of blue up to very dark blue and even black.

Sapphire is found in a wide range of colors and shades of colors. It is a mineral that occurs in the form of Al2O3 single crystals. The color is determined by impurities such as Fe2+, Fe3+, Cr3+, Ti4+ or V4+.

It has a hardness of 9 on the Mohs scale, after diamond.

The rocks where sapphires were found are called pegmatites, which through erosion processes were transported and deposited in alluvium, in the beds of flowing waters. The most important countries in the production of sapphires are Sri Lanka (the old name Ceylon), India, more recently, the USA, Australia and Nigeria.
