Bergkristall Gwindel – Tiefengletscher, Tiefenbach, Realp, Urseren, Uri, Switzerland

 Crystal-clear and highly lustrous gwindel with a beautiful twist on rock crystal in its normal habit. Some triangular faces are slightly more matte than the rest, adding depth and plasticity. A wonderful collector's item from the difficult-to-access, steep, and exposed walls of the Tiefengletscher glacier.
 Clear rock crystal gwindels are less common than smoky quartz gwindels and are therefore among the most sought-after rarities in alpine collections!
