Item Description

A 3.0 cm, pristine, terminated, wedge-shaped calcite rhomb with satin lustre faces is jauntily perched on the end on the sculptural mounded elongated combination matrix. Sparkly tiny quartz points richly cover one side, with green fluorite sections visible below the quartz on the other side. The matrix is granite. Neon orange calcite and purple fluorite fluorescence. Ex Kay Robertson Collection # 11430 and acquired from From the Earth at Tucson in 1988. 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). A very showy and uncommon two-sided combination from the extinct Pb-Cu mines with fluorite and quartz gangues hosted by granite (MINDAT).
