Silver "sheet" on Copper schist (ex Kay Robertson Collection)

Item Description

An interesting and hard to find "sheet" of Native Silver sitting atop Copper schist (according to the label) from the well-known Mansfeld Basin of Germany. The Silver itself measures 4.2 cm at its longest dimension and has a classic old patina. It's not common to get your hands on a matrix piece of this style of Silver from Mansfeld, as many of them are just nondescript and kind of "lumpy". This is certainly a different kind of Silver specimen and would make a great addition to any native elements collection or a suite of German minerals. For reference mining at Mansfeld dates back to around the year 1200 and only stopped in 1969. Ex Kay Robertson Collection (#934). 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). Valued at $600.
