Bazzite is a beryllium scandium cyclosilicate mineral with chemical formula: Be3Sc2Si6O18 (Be3(ScFe)2Si6O18 or Be3(ScAl)2Si6O18). It crystallizes in the hexagonal crystal system typically as small blue hexagonal crystals up to 2 cm length. It has a Mohs hardness of 6.5-7 and a specific gravity of 2.77 to 2.85.Hard to distinguish from blue beryl.Occurs in miarolitic cavities in granite in alpine veins and in scandium bearing granitic pegmatites.
