Millerite on Calcite (rare - old) Hintze & Robertson Coll.

Item Description

Tiny, very bright, iridescent bronzy-brassy Millerite needles are festooned on the sculptural limestone matrix covered with striking stacked towers of small hexagonal, gray pokerchip calcite crystals. Millerite specimens are VERY RARE from the historic silver mines at St Andreasberg. See the Mineralogical Record St. Andreasberg Special Issue, May-June, 2017, Vol. 48, No. 3., Pages 370-371. Most purported specimens have found to be either cubanite or stibnite. Detailed analysis would be required to determine the species. Ex Kay Robertson Collection # 4717 and acquired from Jochen Hintze in Germany in the mid-1960s. 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 rich millerite and calcite. Pink calcite fluorescence.
