Clinohedrite
Clinohedrite is named after Greek "klinein" - to incline plus "hedra" - base, because it was considered to be a kind of tetrahedrite showing an aberrant form.
Clinohedrite forms colourless, white to pale amethystine colour crystals with a brilliant lustre. Exhibits a rich orange colour under short wave ultraviolet light.
