Gwindel, smoky quartz, Adular – Val Giuv, Graubünden, Switzerland
 
Aesthetic hand specimen made of intensely colored and transparent smoky quartz with two perfectly crystallized threads and a large double terminator. The Gwindels are so-called closed Gwindels, the rarest form of this rare quartz variety.
Steps like these are an absolute alpine classic as there are no comparable ones in the world. 
 
The Val Giuv, near Sedrun in the Surselva in the canton of Graubünden, has always been synonymous with the special color and quality of Swiss smoky quartz, which distinguishes it from other quartz.
Under the most difficult conditions, the crystals are recovered by the emitters at an altitude of around 3,000 meters.
