Chrysocolla (old RARE locality specimen)

Item Description

Here we have a fantastic old-time Chrysocolla specimen from The Rammelsberg, a large well-known mountain that lies in the Harz Mountains, near the town of Goslar. According to the entry on both Wikipedia and Mindat.org, mining had taken place on The Rammelsberg for over 1,000 years when it closed in 1988. Silver and Copper were the primary ores to come out of the locality, but there are plenty of attractive secondary minerals found there as well. This piece is an incredibly hard to find example of Chrysocolla featuring gorgeous, blue-green acicular "tufts" and dark green-blue botryoidal aggregates sitting on dark matrix (Tenorite?). It's the ONLY specimen of Chrysocolla that we've ever had to offer from the locality, so if you collect secondary ore minerals, or German / European minerals, don't miss out on this one.
From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974 ( https://www.mindat.org/photo-326405.html ).
