Calcite with Malachite and Azurite

Calcite with Malachite and AzuriteOne 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 havent seen many Copper Rivet specimens on the market, and they typically arent much to look at, but this piece hosts

flame red colored 9 mm crystal of Brookite is associated with dipyramidal crystals of Anatase which show a honey-gold color when backlit

which is one of my favorite phenomena in the mineral world

Specimen # BOL711B161

The majority of the specimens from this find were merely single crystals off matrix

Specimen # BROOK31917

Great quality all the way around with very little damage

Specimen# CO712B23

This piece is notably colorless (it has a very pale golden overtone) compared to virtually everything else I've seen from the Palelni Mine
