Muscovite var: Fuchsite on Glaucophane

Item Description

This piece is labeled as Clinochlore var: Pennine, but it's actually the chromium-bearing variety of Muscovite, Fuchsite. This relatively flat cabinet sized specimen features rich green colored, foliated crystals of Fuchsite sitting atop dark blue-black colored Glaucophane matrix. Glaucophane is an uncommon Amphibole species, and the specimens from Rio Oremo are among the best examples ever seen. This is rare material, virtually unseen on the market, and it's colorful to boot.
