Prehnite "fingers" with Quartz (ex Kay Robertson Collection)

Item Description

An unusual and attractive Prehnite specimen from the metamorphic contact zones in Baluchistan. The piece hosts "water green" color, "fingers" of Prehnite measuring up to 2.1 cm long with associated Quartz. At first, I thought these might be casts after another species, but they are solid prehnite throughout, and have formed in elongated radiating structures. The piece itself is very attractive and unlike any Prehnite I have seen from any world locality. This piece was mined about 15 years ago, and I have not seen many of them available in that period of time. Ex Kay Robertson Collection (#13153). 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 Velt" November-December 2017).
