UV Reactive Agatized Coral — Polished Fossil Specimen

This agatized coral fossil reveals two worlds in one piece.

In natural light, you see preserved coral structure replaced over time by chalcedony — honey-toned agate rims, cellular fossil patterning, and raw mineral edges that tell the story of ancient life turned to stone.

Under UV light, the transformation is dramatic.

The interior fluoresces in vivid blues and purples, lighting up the fossilized coral pattern and revealing details invisible to the naked eye.

This piece was carefully shaped and polished to expose the fossil structure while keeping the outer edges raw and natural. No dyes, no treatments — the fluorescence is entirely natural.

A rare, display-worthy specimen that bridges geology, fossil history, and light.

UV Reactivity

This specimen fluoresces brightly under 365nm UV / black light, revealing glowing internal structure and fossil detail not visible under normal lighting.

UV photos are included to show this effect accurately.

Good to Know

• Color and fluorescence intensity may vary slightly depending on light source

All photos are taken in natural daylight and true UV light — no filters.

Why This Piece

Agatized coral is a snapshot of deep time — once-living coral, slowly replaced by silica over millions of years. This specimen stands out for both its preserved structure and its intense UV response, making it a rare and captivating collector piece.

Perfect for collectors, fossil enthusiasts, or anyone drawn to stones that transform under light.
