A cluster of 20 or 30 Meta-Torbernite tablets rests on the pale base rock of this hand specimen. These tabular crystals reach diameters of 0.2" (5 mm) and are in moderately good condition; oddly, the largest crystals are intact and the smaller ones are damaged or broken. All have the standard tetragonal tabular form, though the crystals seem to be slightly aggregated besides their intersection. All have the standard forest-green coloration and pearly-to-vitreous luster and are at least dimly transparent. There appear to be 2 distinct minerals present, as there are 2 different crystalline habits and 2 different shades of green visible. Along with these is a massive, dull black material that I cannot identify- it may be some sort of uranium mineral.
