Item Description

Bright multi-hued rich green and teal-green bubbly chrysocolla botryoids cover the undulating gossan matrix on this aesthetic and rich miniature specimen from the Helvetia area, near Tucson. Ex Kay Robertson Collection # 6939 and acquired from Kristalle in June, 1973. 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). Specimens of this richness, quality and color are seldom on the market from here. A MUST for the species or Arizona collector.
