Fluorite With Sphalerite
Naica, Chihuahua, Mexico
Small Cabinet, 6.5 x 5.7 x 5.3 cm

An imposing piece with a bizarre, complicated penetration twin or complex growth atop! This is an intergrown cluster of gemmy, pastel green fluorite crystals, to 3.0 cm across, where cubes are modified by octahedral faces. At the base is a splendent, black sphalerite crystal, measuring 1.5 cm across. There is minor damage/contact on the periphery of the fluorite crystals, however, when the specimen is properly aligned, this cannot be seen. What you DO see is that important gemmy green crystal atop, looking right into it to the matrix behind.
