“4.7 x 4.7 x 4.5 cm. A classic and hard-to-find specimen from Neudorf, which is best known for its classic cuboctahedral galena crystals associated with greenish-brown siderite. This is a lesser seen specimen of tetrahedrite featuring a cluster of iridescent, sharp, golden tetrahedral crystals associated with compressed rhombohedral gemmy greenish-brown siderites along with a few small silvery galenas on gemmy white/colorless quartz crystals on matrix. The entire tetrahedrite cluster measures 2.1 cm across. Good crystallized specimens of tetrahedrite are hard to find from this locality. Ex Kay Robertson Collection (#5567). 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). ”
