Cubanite, Calcite - Henderson No. 2 Mine, Chibougamau, Quebec, Canada
 
 Highly lustrous and sharp terminated cubanite crystals of the best quality. The piece impresses with its aesthetics and well-defined crystals. Rarely can Cubanite Kiristalls be found in such a clearly defined shape. A small calcite sits on the thumbnail in contrast to the metallic lustre of the cubanite crystals. Wonderful collector's specimen of this extremely rare mineral.
