Cluster of transparent to translucent Siderite crystals with stepped and modified Rhomb forms dominating. With backlighting this glows a deep honey-yellow color and is quite lustrous. In good shape overall there are some rough spots but none are major. The Siderite from this locale is some of the best in the world. The largest flattened rhomb on this piece is 3.1 CM across, and has sharply stepped faces.

An exceptionally fine, bright metallic hexagon of Pyrrhotite dusted with a few small Siderite crystals. Ex Larry Conklin, Terry Szenics collection. In excellent condition, this is an fairly old vintage Brazilian specimen from Morro Velha, and is the sharpest with the best luster I have seen. Morro Velha has the distinction of being the longest running Gold mine in the world, it is well known for good Siderite specimens but Pyrrhotites of any size are rare. This is a nice Pyrrhotite from anyplace but incredible for Brazil. In excellent condition.
