Item Description

A cool old Cornish specimen of Wavellite associated with Turquoise (var: Rashleighite). Originally Rashleighite was a valid species, now defined as an iron-bearing Turquoise and an intermediary between Chalcosiderite and Turquoise. This piece features beautiful sky blue patches of this Turquoise varietal which have formed in between thin crystallized layers of "needle"-like white Wavellite in Quartz matrix. Very hard to find on the market, and a must-have for any collection of minerals of Cornwall or a general phosphate collection. Ex Kay Robertson Collection (#2185). 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).
