This small find came out around 1999 and was first mislabeled as smithsonite. It turned out to be unusual;, cuprian rich calcite in sharp crystals - quite a novelty for calcite! Cuprian calcite had been found before in good form only rarely, and never as intensely colored as this. Sitting on matrix, is a plate of uniformly bladed, lustrous, intergrown, crystals of green, calcite. Minor smears of malachite on the underside gave a hint that the coloring agent of the calcite was copper. It is an exquisite, 3-dimensional mound complete about 300 degrees around. 9 x 6.2 x 6.2 cm
