Description

Fantastic glass-clear rock crystal group. Because of its excellent transparency in most of the crystals a few (clay?)-inclusions (as far as I can see seperating some crystals) are shining through from several angles. Nice, natural etching and striations on some surfaces.

Minor chipping on a few edges.

Rock crystal from this area is very rare (smoky crystal is more common there).
