Quite uncommon, Fluor-elbaite has been found only a few places around the world. The crystals in this cluster are a deep blue-green, with great luster and excellent terminations. The Fluor-elbaites are gemmy to translucent, and the parallel growth of the crystals gives the specimen a very architectural look. There is a minor amount of wear on just a few of the edges, but this is minor as this piece is considered among the best of species for this tourmaline variety (per Jim Houran, comments). A very fine specimen.
