This is a very interesting specimen, mineralogically. All of the spongy mass has a goldish iridescence. I believe these to be Siderite or Calcite, which are elongated scalenohedral crysals grown in parallel. The bulk of the specimen is a large smoky Quartz crystal upon which neat little 1-4mm clusters of Eosphorite are grown.
