Item Description

An elegant magnesite and quartz thumbnail from Brumado. Variably-sized tabular, gem, colorless magnesite rhombs are beautifully attached to a quartz point, which in turn, has smaller quartz crystals attached to it. Ex Kay Robertson Collection # 8453 and acquired from Brazilian dealer Carlos Barbosa at Tucson in 1978. 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).The striking large rhomb really imparts pizzazz to this cutie.
