Dealer Bill Larson obtained this piece from a miner in Russia, who said he collected it in 1985-1988. I have seen only a few others of this magnitude for the species, from the region (and they seem to be overall the best for species, considering crystal size and habit). The brucite crystals on this matrix specimen are absolutely outstanding and reach 4.0 cm across; and have pearlescent luster with gemmy, pastel green interiors. Brucite is fairly uncommon worldwide and sharp crystals even more so - usually it forms jumbly crusts. As a whole, this is an imposing piece for the transparency and form of so many good crystals richly aggregated on a bit of matrix. It is much better in person!
