A superb specimen of a super-sharp, tan, talc pseudomorphs after dolomite rhombs. The largest rhomb is 1.4 cm. This fine old-time piece is from a renowned locality for this rare replacement - the Johannes Mine, Bavaria, Germany. The dolomite pseudomorphs are so sharp that they look man-made, but the beautiful patina is diagnostic, that it is, in fact, natural and not carved from a massive talc block. It once was called "steattite." Ex. Mullane Collection and accompanied by two labels in German.
