Conichalcite (ex Kay Robertson Collection)

Item Description

Here we have a nice Conichalcite specimen from this lesser known locality in Sonora. There is a decent coverage of rich green color, sparkling, green, radiating crystal groups of Conichalcite measuring up to 8 mm across on matrix. The main vug is undamaged, but there are some spots on the outer portion of the piece where it is contacted. If you collect Mexican minerals, this is a cool esoteric specimen that would make a nice addition. Ex Kay Robertson Collection (#1682). 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).
