An excellent small cabinet display specimen of terminated, prismatic Neptunite crystals measuring to 2.6 cm from the California State Gem Mine in San Benito County, California, USA. Two of the Neptunite crystals are double terminated and all have the characteristic black lustre with occasional flashes of bright metallic red. These contrast perfectly against the snow-white Natrolite covered matrix. In association with the Neptunite, at least five orange microcrystals of the rare mineral Joaquinite-(Ce) are partly exposed from the white Natrolite. A superb specimen.

Neptunite from California State Gem Mine, USA
from the California State Gem Mine is one of the great black-crystal classics of American mineral collecting: sharp, monoclinic prisms with a lacquered, almost metallic-looking luster, rising from white natrolite and, on the most coveted pieces, accompanied by blue benitoite and tiny honey- to orange-brown joaquinite-(Ce). Thick crystals read as jet-black across the room, but fine edges and broken splinters can flash deep reddish brown to maroon, a color clue that separates neptunite from the tourmaline-like impression it can give at first glance.
