Item Description

Certainly, the finest examples of Neptunite ever found are those from the now closed Gem Mine in California. These are the most well-known crystals of the species, and they are truly beautiful and impressive specimens, renowned for their quality and beauty. This piece hosts several, 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 1.7 cm long. For the quality and aesthetics, this is a nice specimen of this fast-disappearing material. Good condition for the most part, though a few of the crystals are not complete, though most of the central crystal are well-terminated and undamaged.
