A pyrite sun opens across a dark slab of layered shale. Fine metallic ridges radiate from an uneven central cluster toward a roughly rounded rim. Some sections catch pale brass highlights, while others shift toward muted olive and deep brown. The changing reflections make each narrow ray visible without turning the specimen into a perfectly regular disk.

The radial ridges meet rough stone around the perimeter. Small breaks interrupt the edge, and a few larger crystalline fragments rise near the center. Beneath the mineral, the shale separates into thin irregular layers. Their matte gray surfaces provide a strong contrast to the sharper glints of the metallic form above them.

Several loose chips rest on the charcoal surface below the slab. Short contact shadows keep them distinct from the fine texture of the background. Light arrives from one side and grazes the upper edges before fading into the lower-right corner. The close portrait view gives the specimen enough surrounding stone to show its physical setting, while drawing attention to the surprisingly elaborate pattern made by the mineral rays.
