Here is a fine, large cabinet-sized specimen featuring a rich covering of clear aragonite crystals capped with opaque white plumboan aragonite (tarnowitzite). The crystals are sharp pseudo-hexagonal twins with the appearance of hexagonal pseudo-dipyramids. The crystals have a bright, wet-look luster. The matrix is rich in reddish-orange mimetite with patches of green duftite. This is an interesting Tsumeb specimen of this un common aragonite variety. From an old collection that was put together between the 1930s and 1960s by Carey Melville, a professor at Clark University. Old hand-written label included.
