Item Description

This is a seldom seen specimen of the rare lead iron arsenate species, named for Fran├žois Beudant (1787-1850), a French mineralogist at the University of Paris. The species is found in various metallic deposits as a secondary mineral all over the world, but its varying crystal habits and colors make it a notably diverse species, as it rarely looks the same from any two localities. The crystals from Tsumeb are typically brown to dark golden-brown in color, but I've seen golden and greenish colored crystals from this mine as well. This piece hosts micro crystals of dark reddish to golden-brown colored Beudantite that are best seen under the microscope. We've photographed the piece with a Canon MP-E 65 mm macro lens to better illustrate the quality. A cool rarity for any Tsumeb collector. From the collection of Shields Flynn.
