Several tiny Meta-zeunerite tablets rest on the dark brown base of this thumbnail specimen. They are generally in good condition, shnwing little damage, and do not exceed 0.1" (3 mm) in diameter. Though some appear to be intensely intergrown, those that are not show excellent tetragonal tabular form. Their grass-green color and pearly luster are very similar to that of zeunerite, torbernite, and meta-torbernite. It would appear that another secondary copper mineral is present- it is likely olivenite, which is rather commonly found at this locality. The piece is affixed inside a plastic specimen box with a removable putty.
