JFD64AN9: The Bou Nahas mine exploded onto the world collecting scene relatively recently. This Marcasite is phenomenal, with a multitude of crystals, all with Sperkise twinning, which are grouped together forming a very sharp and aesthetic elongated column. Since the mine started operating not many years ago, it is not yet possible to know for certain how well these marcasites will be preserved, but at the moment they do not seem to show signs of decomposition.
