Fluorite With Sphalerite and Minor Pyrite
Naica, Chihuahua, Mexico
Small Cabinet, 9.2 x 8.2 x 4.1 cm
Gemmy, pastel green fluorite crystals to 4.0 cm across are nicely perched on splendent, black crystals of sphalerite to 1.0 cm across with minor brassy pyrite crystals to .2 cm across. The fluorite crystals appear to be cubes modified by octahedral faces. Only the very smallest of peripheral damage/contact exists. This dramatic uprising cluster is very impressive in person, and has a bit more color than indicated in the photo. There is a lot of fluorite for the price, on matrix, here.
