Bergkristall Gwindel – Val Strem, Tujetsch, Surselva, Graubünden, Switzerland

 Crystal-clear and highly lustrous gwindel with a beautiful twist. Some triangular faces are lightly dusted with sparkling chlorite, adding depth and plasticity. A wonderful collector's item from the difficult-to-access, steep, and exposed walls of Val Strem.
 Clear rock crystal gwindels are less common than smoky quartz gwindels and are therefore among the most sought-after rarities in alpine collections!
