System:TrigonalColour:Tin white
Hardness:2


Tin white metallic plates with perfect basal cleavage, mm thick to cm in width. Crystals have hexagonal outline, often with trigonal growth features. Impossible to visually identify. All species in tetradymite/ tellurobismuthinite family must be probed and x-rayed for positive identification.
