The aluminium SILICATE mineral, Kyanite (derived from the Greek 'kyanos' meaning 'blue') is used in the manufacture of spark plugs, porcelain and other refractories; it has the same chemical composition as ANDALUSITE and SILLIMANITE. It's long-bladed - (usually blue; like this one from Brazil) crystals (triclinic system) are distinctive. Hardness is 4-5 along the length of the crystal and 6-7 across it, lustre is vitreous to pearly, specific gravity is 3.5-3.7 and cleavage is perfect in one direction.
Kyanite occurs in gneisses, schists and granite pegmatites: it is an indicator of deep-seated, regional metamorphism of clay-rich sediments and it often occurs with Garnet and Staurolite in crystalline schists.
