Once considered its own species, this sphaerosiderite is now considered to be a microcrystalline, botryoidal variety of siderite. It is classic and unique material, though, and comes at its best from this old mine in Romania. This specimen is complete all around, and is a gorgeous and rich example of both the species variety, and of the classic association from this particular mine. I have seen these pop up from time to time in old collections, but never one so good as this one.
