Stilbite on Smoky Quartz (ex Kay Robertson Collection)

Item Description

Zeolites are not often seen in Alpine kleft deposits, but Stilbite has been found in many European Alpine localities. This piece features tan-brown-beige colored "sheaves" of Stilbite measuring up to 7 mm sitting atop sharp, lustrous, gemmy Smoky Quartz crystal matrix. A cool oddity from Switzerland. The label states that the piece is from "Valetscha" (possibly Val Casatscha?) Ex Kay Robertson Collection (#11821). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
