A large green fluorite crystalis nicely perched on a black host rock. The fluorite is transparent a a pale lime-green in color, but shows no crystal form. Also, its surface is quite rough giving it a dull appearance. The host rock is mostly composed of quartz, and the surface is largely covered by thin, empty shells of (probably) milky quartz. Apparently, all of this was embedded within (and intergrown with) some other mineral, likely calcite, which has been etched away, exposing the fluorite. There are actually quite a few small crystals of fluorite, some of which are tiny cubes.
