The History
The Jurassic Coast, a UNESCO World Heritage site, preserves one of the richest fossil records on earth. Ammonites like Promicroceras thrived in the seas nearly 200 million years ago, their spiral shells becoming enduring symbols of evolution, resilience, and natural design.
Through pyritization — the replacement of shell material with iron pyrite — this ammonite was transformed into a metallic fossil of striking beauty. To wear it is to carry a fragment of Earth’s deep past, preserved in glittering detail from the dawn of the Jurassic era.
