Neptunite comes from only a handful of localities worldwide, but the very best specimens of this rare silicate are found at the Benitoite Gem Mine. There are several dozen crystals with a nearly square cross section on this excellent piece, 2 of which are .4" long. The crystals have a bright luster and are colored a rich jet black. The crystals contrast nicely with the matrix of white natrolite in which they grew. Since the mine closed in the early 2000s the supply of specimens of neptunite has all but disappeared.
