This cabinet specimen consists of a crust of specular Malachite that covers a brown, layered siliceous base. The Malachite crust has a definite compact, crystalline habit and shows some slight mammillary shapes on its surface. It has a moderately deep green color on its outer surface and a sparkle that appears to be caused by a druse of perhaps thousands of tiny, needle-like crystals. Its broken edge surfaces show a darker green color and a pearly luster.
