Tetrahedrite with Pyrite and Quartz (classic material) (ex Kay Robertson Collection)

Item Description

A wonderfully showy and classis full cabinet sized display specimen from Park City featuring dozens of sharp well-formed crystals of silvery-grey tetrahedral crystals of Tetrahedrite measuring up to 4 mm which have a semi-selective deposition / coating of sparkling golden Pyrite and sitting among sharp, prismatic white Quartz crystals on matrix. This excellent combo is highly sought after from the Daly-Jude Mine and pieces like this are seldom available on the market these days, as the mine is long closed. Very little damage to speak of, and just plain pretty, especially up close. Ex Kay Robertson Collection (#735). 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).
