“4.0 x 2.7 x 1.3 cm. 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 Malad (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).
