  • Size:5.5 x 4.9 x 4.0 cm
  • Size Description:Large Miniature

Description:A 3.3 cm, sharply terminated, bright and rich copper-in-calcite crystal is aesthetically set on floater copper crystals with striking sculptural form. The intergrown copper crystals have rich mellow patina and an amazing melted look with cavernous areas, where other crystals or matrix have been dissolved away. The bottom end of the calcite is contacted and that's embedded epidote in the side of the calcite. Every turn of this very fine combination piece offers a totally different pespective! Classic, excellent and most desirable old-time material from Copper Country. Ex Cal Tech Collection (which contains a number of old copper country minerals donated in the early 1900s, mostly by TH Cole). Valued at $1250-1500.
