Item Description

Without a doubt, the finest and most well-known crystals of Neptunite ever found are those from the now closed Gem Mine in California. These attractive and top-quality crystals are truly beautiful and impressive for the species. This piece hosts a pair of fine lustrous, prismatic crystals of dark reddish-black Neptunite aesthetically sitting on a layer of white Natrolite atop muted blue-grey Crossite on matrix. The largest crystal measures 1.2 cm long. For the quality and aesthetics, this is a nice specimen of this fast-disappearing material. Good condition for the most part, though one of the crystals is not complete, as it is contacted on the front edge.
