This stalactite is composed of chrysocola in rounded overlapping masses. It has a typical sky-blue color, although some patches are lighter in hue than others. The overall luster is dull, and while there are no crystals, my loupe reveals that the surface is composed of tiny bumps, each of which has a somewhat shiney appearance. There are several dark green patches of malachite; under the loupe, these resolve into a druze of very tiny transparent green crystals, still too small to reveal their form.
