Clinoclase (ex Kay Robertson Collection)

Item Description

Please note: This specimen came labeled as coming from the Lautaro District in Chile, which is a city and commune of the Cautin Province in Chile's Araucania Region.  With that said, this miniature sized piece features a vug loaded with beautiful, rich blue colored crystals of this beloved copper arsenate. The crystals are best viewed under magnification, and we've photographed them with a Canon MP-E 65 mm macro lens to better illustrate the quality. Ex Kay Robertson Collection (#10878). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020.
