A large, uncommon, pretty and very rich specimen of atacamite from AUSTRALIA. The crystals show two generation of growth, with the upper part of the specimen having the second generation of smaller, darker platy crystals on two "knobs" that are accented by the lighter-colored crystals on the bottom of the specimen. The back of the specimen is fine as well, and it can actually be displayed that way. 9 x 8 x 3.3 cm
