Cuproscheelite (RARE Mexico - fluorescent) Kay Robertson Coll.

Item Description

VERY RARE green copper-included scheelite from an unknown locality in Sonora, Mexico. The crudely tetragonal, hefty for its size crystal is richly included with bright green oxidized copper. Ghostly white fluorescence, as you would expect. Ex Kay Robertson Collection # 6346 and acquired from the Dawson's in 1971 at the Glendale Show. 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). Rare and colorful scheelite from Mexico!
