Rare old material, from one of the few places where you get copper in calcite! This matrix specimen features glassy and gemmy, mostly colorless crystals of "nail head spar" calcite, to 2.5 cm in length, which has grown on top of dendritic copper. Some of the copper is invested with an exquisite greenish malachite patina. In a few cases the copper has actually included the calcite, giving the latter a pinkish glow. The calcite fluoresces a beautiful rich orange color, as a bonus. One or two calcite crystals exhibit damage at their terminations but that does not impact the specimen negatively, and it is a relatively large example for this style. They were said to have been found in the 1950s or before, and we have seen few for sale over the years.
