A group of mirror-bright pyrite crystals, stacked in a tower. The cystals are predominantly octahedral, with dodecahedral and pyritohedral modifications. The specimen is crystallized all-around, with some tiney sphalerite crystals on the back. In exceptional condition, a couple of tiny chips can be found with a search – this specimen is that good. The point underneath where this was originally attached to surrounding rock has a crystallization pattern as well, so it detached sometime before all crystallization processes were complete.
This is a gorgeous cluster of pyrite crystals.
