I LOVE THESE THINGS! WHAT A NEAT EXAMPLE OF INTERESTING MINERALOGY, having talc replace a hard mineral like quartz!?! This is an incredibly rare pseudomorph of talc after quartz on massive talc from Germany. These pseudomorphs are quite old, having come out of the ground prior to the 1930s. Unique to this location, the crystals are very sharp and have a soft vitreous luster. One of the hardest pseudomorphs to find in any condition and this piece is nearly perfect, AND OF LARGE SIZE. As you can imagine, this is a "must have" for any pseudomorph collector. Ex. P. Pohndorf collection (1931). E. Mitchell Gunnell and Hauck labels included with piece.
