Sparkling, gemmy and transparent crystals of pinnoite, a very rare borate, form a palm-sized specimen here. The crystals individually reach 3-4 mm and are very sharp. They are embedded in a matrix of other borates (massive). Rare, old material from this important borate locality. Obtained in 2002 from Fersman Museum. Pinnoite, in crystallized form, for some reason does NOT occur at the other most famous specimen locales for borates, in the Death Valley and other mines near Boron, California; and in Turkey.
