A BEAUTIFUL and AESTHETIC, old-time, Copper Country specimen of a lustrous, striated and translucent, 4.3 cm, colorless, twinned calcite scalenohedron. It is very nicely set on copper with matrix, and has included copper inside. Several faces of the calcite crystal are preferentially peppered with tiny copper crystals, which really adds character. The yellowed, antique label tells you that this is a 100 year old plus specimen. 5.0 x 4.0 x 3.5 cm
