Unusually sharp, lustrous (for Columbite) and perfectly terminated, this is a choice single crystal of the specie. Ex University of Delaware Museum, the condition is outstanding especially given the fragility of Columbite. A heavy piece (just over 74 grams despite the small size), a textbook perfect example from the Brazilian pegmatites of Rio Doce.

A single, blocky but somewhat tabular Colombite crystal. Distinct although rather crude, the crystal is fully terminated and moderately lustrous. An older piece from Sao Jose do Safira (Brazil) this is a very good miniature of this commercially important pegmatite mineral that is not often considered "pretty".
