This is an incredible multiple-species specimen. At least two dozen partial or complete crystals of benitoite are scattered over this specimen. The largest crystal I found was just under 0.4" (1.0cm). Next, there are over 100 crystals of neptunite ranging in size from tiny to one monster 1.6" (4.1cm) in length. Many of these neptunites have excellent terminations. Finally, there is a small amount of tiny, acicular crystals of joaquinite on one edge of this specimen. These joaquinite crystals show a very dim yellow-brown fluorescence under short-wave ultraviolet light. All of these crystals are thrusting out of a bed of massive white natrolite. The natrolite is deposited on an altered serpentine host material. This is quite an impressive specimen.
