Item Description
Rich emerald-green, lustrous, translucent dioptase crystals form an aesthetic thumbnail from classic old finds at Reneville in the 1950-70s. Ex Kay Robertson Collection # 7158 and acquired from French dealer Roger Titeux at the Tucson Show in 1974. This was probably new material, then. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record).
