Babingtonite on Quartz (ex Kay Robertson Collection)

Item Description

An attractive and fine quality specimen featuring superb, sharp, lustrous, bladed, jet-black colored crystals of Babingtonite measuring up to 9 mm with Quartz on matrix from the Kandivali Quarry. The green material might be Pumpellyite or Julgoldite, but it's hard to know without analysis. Babingtonite is an UNCOMMON silicate (it's actually a member of the Rhodonite group) from the Bombay area quarries and this is a superb example. The Bombay area quarries are closed, due to population growth. Ex Kay Robertson Collection (#8706). 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).
