Mining of these fine copper thumbers has stopped, at least for the time being - which is sad, because they are just so good. One side of this completely crystalllized specimen shows the classic herringbone pattern, and the other, chunky little spinel-twinned crystals! (sorry for the fuzzy shot of these little crystals but they are quite pretty and interesting in person). 2.8 x 1.2 x 1.1 cm
