Description
On first glance I had no idea, what kind of species this could be. High metallic lustrous, slender crystals on Quartz rich matrix. I asume, this was the reason why the specimen has been analyzed. The Skutterudite crystals here are over 3 cm long and showing an interesting undulated surface. I never saw this kind of stuff over the years. Highly interesting and RARE material, practically not offered for sale due to the lack of specimens.
