Description

The vast family of tourmalines includes the world-famous, colorful crystals of elbaite and related species from pegmatite veins, as well as a series of unusual terms, less spectacular but of high scientific value. The most exotic are no doubt the vanadium-bearing tourmalines, typicaly exclusive of the Lake Bajkal area and hardly available to collectors.

A recent study on a poorly characterized tourmaline from an obscure U prospect on the shores of Lake Onega in nothern Russia led to identification of chromium-bearing vanadio-oxy-dravite, the second world find. We identified a small specimen from the same occurrence in an old collection where it landed some years ago following distribution of drill-core samples to the market. 

Here we offer vanadio-oxy-dravite as tiny, emerald green crystalline grains with other unidentified phases on pink dolomite crystals. Very scarce materal available!
