The hardest crystals become the softest. A superb specimen of a super-sharp, complete all-around, pseudo-hexagonal, light brown, talc pseudomorph after a quartz crystal. This fine old-time specimen is from a renowned locality for this rare replacement - the Johannes Mine, Bavaria, Germany. The quartz pseudomorph is so sharp, that it looks man-made, but the beautiful patina is diagnostic, that it is, in fact, natural and not carved from a massive talc block. This is very old material. It once was called "steattite." Ex. Mullane Collection accompanied by a label in German.
