Hundreds of small, round Torbernite blades make up the crust that partly coats the gray-black host rock of this specimen. These blades do not exceed 0.2" (5 mm) in diameter or 2 mm in thickness, and are generally in good condition, though a few of the most exposed ones are damaged. Their tetragonal tabular form is fair, as most of the blades are rounded due to intergrowth. They possess the standard grass-green color and pearly luster of their species, and are moderately to dimly translucent when not in clusters. The host rock appears to be made of a gray quartzite that is suffused with a darker, almost black mineral that I cannot identify- it might be a decomposition product of another mineral.
