@themineralminute: Mined over 7,000 feet (2130+ meters) on a sheer cliff-face in the Swiss Alps, this rare 10+ lbs (4.6+ kg) dark smoky quartz crystal matrix specimen was found and brought down entirely by hand. This top-tier museum-quality mineral features a stunning aesthetic contrast of glass-like single crystals against a monster smoky gwindel quartz. The extreme danger of this high-altitude alpine crystal hunting, and the legendary rarity of the Swiss gwindel, make this a world-class crystal investment. • • • #smokyquartz #quartz #crystaltok #fineminerals #rarecrystals
