Bazzite

Bazzite is a beryllium cyclosilicate with chemical formula: Be3Sc2Si6O18 ). 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.

It is hard to distinguish from blue beryl.

Occurs in miarolitic , in alpine veins and in scandium bearing granitic pegmatites. It occurs associated with quartz , muscovite, hematite, fluorite

It was first described from an occurrence in Baveno , Italy. Named after the discoverer, the Italian engineer Alessandro E. Bazzi
