DT Dravite-Schorl w/ Biotite (RARE 2018 Find) 86 grams

Item Description

Rare doubly terminated tourmaline from a 2018 new find at this obscure Espirito Santo State locale. Tourmaline is not listed in the MINDAT locale. This very sculptural 360-degree miniature specimen is dravite-schorl. The aesthetic, stepped parallel-growth trigonal crystals have very high lustre and densely striated prism faces. The specimen form and lustrous modified pyramidal terminations add much characcter. Pearlescent biotite plates cover part of the basal termination and there are patches on the sides. The specimen appears to be black schorl in most photos, depending on lighting type, background and incidence. But, other photographic parameters reveal the beautiful mahogany color flashes of dravite of the piece. Specimens would have to be analyzed for a definitive composition result, but are probably a combination of dravite and schorl. Mass is 86 grams.
