Torbernite (old classic) (ex Kay Robertson Collection)

Item Description

A great old classic from Cornwall! This piece was only labeled as coming from Cornwall, and could possibly be from the Old Gunnislake Mine in Calstock, but it's difficult to say as we're not Cornish experts. Dozens of fine quality, well-formed, sharp, tetragonal blades of a gorgeous chrome-green color can be seen on the underlying matrix. We have photographed the piece with a Canon MP-E 65 mm macro lens to better illustrate the quality. Very attractive and a must have for any collector of Cornish minerals or old European classics. Ex Kay Robertson Collection (#7220). 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).
