Item Description

Please note: This vail of crystals is labeled as coming from "Auerbach nr. Stolberg, Harz, Germany". Thanks to Wolfram Lange who provided this information.

The crystals are from "Auerberg (a mountain) near Stolberg, Harz, Sachsen-Anhalt, Germany. The Quartz crystals occur here in an rhyolithic rock." This glass vial is filled with several fairly sharp, well-formed, "floater" crystals of grey colored bi-pyramidal Quartz (pseudo Beta crystals) measuring up to about 6 mm. Ex Kay Robertson Collection (#4489). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020. See the article in the March-April, 2007 Mineralogical Record ( https://www.mineralogicalrecor... ), and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017.
