We all know the great Carrollite specimens from the Congo and I declare, this specimen is not comparable in quality with these. But in aspects of rarity of course and here we have an old-time German piece, formerly described as "Sychnodymite". This is an ULTRARARE classic locality piece with metallic masses richly embedded in typically matrix. This great piece comes with two antique labels and the original label of Dr. Grundmann as well. This is very rare stuff and actually not seen for sale on the market.
