Sapphirine is a magnesium-aluminium silicate and is therefore not related to sapphire/corundum. The name was chosen in 1790 by the discoverer of the mineral because of its blue color and hexagonal crystals. Sapphirine is quite hard, brittle (Mohs=7.5) and has a monoclinic crystal structure. In addition to blue tones, greenish or gray/black color nuances also occur.
