Indicolite Tourmaline (ex Kay Robertson Collection) (19.83 grams)

Item Description

A wonderful, gemmy lovely blue color prism of classic Indicolite Tourmaline from Braizl. The crystal is in great shape overall with only a little bit of roughness here and there. Good quality all the way around, and would make a fantastic little addition to any gem crystal suite, a Tourmaline collection, an assortment of Brazilian minerals or a thumbnail collection. Ex Kay Robertson Collection (#1996). 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).
