Quartz var. Gwindel -Staldental, Maderanertal, Uri, Switzerland
 
 Clear and lustrous Gwindel cluster with adularia from the Maderanertal in the Swiss canton of Uri. Most of the contact and breakage points are rehealed. The Gwindel shows a nice twist. Gwindel are a special shape of growth of quartz and are absolute alpine classics for a good reason.
 Under adventurous conditions, the crystals are dug by hand from the so-called "Strahlers" at an altitude of approx. 3,000 meters.
