A group of very sharp malachite pseudomorphs after azurite in a vug, from the Milpillas mine.  The crystals on these pseudomorph specimens usually tend to have a more messy, rounded appearance, to say nothing of the frequent scuffs.  These individual crystals are a bit smaller, but they have that Toussit (or even Tsumeb) sort of blocky sharpness— plus, being situated in a vug, they are all damage free.
