Galena on Quartz coating Flourite (ex Kay Robertson Collection)

Item Description

Neudorf Galenas are icons in the mineral world, and certainly highly sought after by collectors. This piece features many sharp, well-formed, silvery-black colored cuboctahedra of Galena measuring up to 1.1 cm on edge which are sitting on a layer of sugar / drusy Quartz that is coating Fluorite crystals on matrix. The lable refers to the Quartz as forming "casts" after the Flourite, but the Fluorite is still present, so it's simply a coating. Most of the Galena crystals are undamaged, but there are a few tiny imperfections here and there. The combo and the arrangement of the piece makes for a lovely miniature of this classic old time material. Valued at $500. Ex Kay Robertson Collection (#8989). 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).
