Description

Very elegant cabinet featuring elongated, double terminated crystals of calcite elegantly perched on chalcopyrite-laden matrix. The elongated individuals display complete, sharp terminations and are perfect all around, with only occasional peripheral brusing, which is negligible.

In excellent conditions, this choice specimen comes ready for display on a plinth. Alternatively, one could trim the specimen and make two large miniatures, however I prefer to leave this choice to the lucky buyer.

From the former collection Kasper (CH), assembled in the 70s.
