Sapphire is a variety of corindone, which chemically is aluminum oxide (al₂OR₃) strongly allocromatic. It presents hardness 9 on the Mohs scale.

The Mohs scale is an empirical criterion for the evaluation of the hardness of the materials. It takes its name from the German mineralogist Friedrich Mohs, who designed it in 1812. It takes on as a reference the hardness of ten minerals numbered progressively from 1 to 10, such that each one is able to scratch what precedes it and is scratched by what it is follows.

The term sapphire (devoid of other adjectives) identifies the blue-blue variety of the corindon,

Sapphires can in fact possess the most diverse colors, from pink to orange, purple, green, yellow to colorless white.

The blue-blue color typical of the gem derives from inclusions of hematite and rutilo. In the event that inclusions are oriented in particular ways, the phenomenon of astterism can be presented.

The name sapphire It probably derives from the Greek term σάπφειρος (sappheiros), that is "blue", or from the Eraic ספδ (know), ie "the most beautiful thing".
