Tetrahedrite (rare locality specimen) (ex Kay Robertson Collection)

Item Description

A classic and hard to find specimen from the famous locality at 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, and despite a few incomplete crystals, it's in good condition overall. Good crystallized specimens of Tetrahedrite are hard to find from this locality, and this one is certainly worth picking up if you collect German minerals or worldwide sulfides. Priced at $650 in the inventory. 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).
