A stunning gem quality smoky quartz thumbnail showing the rare closed-gwindel style of formation of quartz, sometimes (rarely) seen in high-altitude Alpine deposits and particularly known from Swiss locations. This is a large, full thumbnail of fine quality, and few such seem to be recovered. This is a true "jewel" of a quartz. From a single special pocket seemingly found in 2016, this was one of a suite of 5 pristine and similarly gorgeous specimens, all showing different crystal habit, that Brent purchased fresh from the collectors (called, strahlers) through the Swiss dealership Siber & Siber in 2017. An excellent summary of the more technical aspects of these amazing styles of quartz, called Gwindels after the German word for "twisted," can be found here: http://www.quartzpage.de/gwindel.html
