Calcite with Malachite and Azurite

One of the best crystallized Calcites that I have seen from the Copper Rivet Mine, located several miles north of the Cashin Mine, along Slat Creek, west of Highway 141. This lesser-known locality apparently produced some specimens in the late 1990s when a few enterprising individuals were able to liberate pieces in their free time. I haven’t seen many Copper Rivet specimens on the market, and they typically aren’t much to look at, but this piece hosts a 4.2 cm Calcite scalenohedron, which is certainly one of the best Calcite crystals that I have seen from this obscure locale. Minor associated green Malachite and blue Azurite make for a nice touch and signify the validity of the piece. Don’t miss out on this one, as I feel that there will be no more, I only know of two this nice that came out. Specimen# CO712B88
