Pyrite Concretion

Item Description

The small, sparkling, sharp, modified, metallic pyrite crystals have formed in amazingly concentric "rings" or "bands" on a distorted "sphere" of shale. The specimen resembles some kind of strange planet, and almost has an organic look to it. A very cool "floater" specimen and certainly unusual, as this one has two attachment points or "bald" spots. These fairly new and incredibly interesting pyrite concretions are some of the most unique specimens that we have seen from any locality.
