Type Locality:

ⓘ Buca della Vena Mine, Ponte Stazzemese, Stazzema, Apuan Alps, Lucca Province, Tuscany, Italy

General Appearance of Type Material:

Acicular crystals, elongated [010], black in colour with bluish metallic luster. The bluish colour apparently arises from a superficial very low hydrothermal alteration of the crystals.
