Deep magenta crystals of Talmessite are festooned on a pinkish Dolomite matrix from one of the best world localities for the species. Talmessite is an uncommon hydrous calcium-magnesium arsenate and the Bou Azzer Mine has produced exceptional specimens for the species. This piece consists of low-profile, interconnected botryoids composed of disk-shaped, rich magenta colored crystals with very good luster that scintillate in any incident light. The botryoidal clusters average about 1.0 cm across and this small cabinet piece is an excellent example of the mineral from this great locality. Ex. Victor Yount collection with label. Victor, in his heyday as a dealer and collector, specialized in Moroccan material in the 1970s and 1980s, and brought much of it to market. This was from his personal Morocco-focus collection, which he began to sell off in Tucson, perhaps around 2010 or so.
