A genuine ammonite fossil from the world-renowned Jurassic Coast of England, formed during the Early Jurassic period around 195 million years ago.

The History
The Jurassic Coast of Dorset, a UNESCO World Heritage site, preserves one of the richest fossil records on earth. Ammonites like Promicroceras thrived in the seas of the Early Jurassic, their spiral shells becoming symbols of evolution, endurance, and natural design.
Pyritization — the replacement of shell material by iron pyrite — endowed this fossil with its natural metallic luster. The result is a piece that is both an ancient relic and a jewel of geological artistry, perfectly suited to be worn as a pendant nearly 200 million years after it was formed.
