A unique and rare specimen featuring a large complete sphere of crystallized Pyrite still attached to its grey Shale matrix. It’s unusual to find these crystallized Pyrite balls, but still attached to its matrix even more unusual. A fantastic show piece with great contrast, metallic luster and symmetry. In excellent condition.
