Columbite - well-formed prismatic crystal
Rio Doce District
Minas Gerais, Brazil
3.8 x 2.7 x 2.2 CM (miniature)
price: $550
Pre Tucson
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.
