This is a remarkable floater cluster of large, translucent, bluish-gray wardite crystals, to 2 cm on edge and slightly more across the octohedron's diagonal, from this famous locality which certainly has produced the world's best for the species in my opinion. The front is very lustrous and bright, while the backside is covered with a sprinkling of sparkly siderite microcrystals. There is no contact point - the cluster is entirely a floater free of matrix attachment points, terminated all around! The major crystal here is almost an INCH in size! This specimen features the largest fine crystal for the species that I have personally seen, for sale or otherwise. It was collected in the field by French collector, from whom I obtained it in Munich when he sold a part of his longtime personal collection.
