This beautiful combination specimen from Brazil features well-formed siderite crystals with sharp definition, bright luster, and attractive surface patterns.

They are associated with several pyrrhotite crystals, while small white albite crystals add additional contrast. A very aesthetic and well-balanced combination specimen.
