Description
Remarkable gwindel-type smoky quartz crystal (twisted quartz) combined with classic smoky quartz prisms.
The whole is buoyant and intact. The underside of the specimen is entirely crystallized, very attractive.
Quartz crystals, including a gwindel, a mineral species from the Talèfre glacier basin in the Mont Blanc massif at Chamonix, Haute-Savoie.
