Vanadinite (classic material) (ex Kay Robertson Collection)

Item Description

Taouz Vanadinites are certainly some of the most distinctive examples of the species in the world. The contrast of the strong red crystals against the manganese / iron oxide matrix makes for eye-catching specimens. This piece hosts sharp, lustrous, tabular, hexagonal, orange-red colored crystals measuring up to 4 mm across sitting on stalactitic black "spires" of black manganese or iron oxide with associated Calcite. There are some spots of damage, but it's still a good representation of this classic material dating back 30 years or so. Ex Kay Robertson Collection (#9902). 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).
