This pendant will feature an authentic Promicroceras ammonite fossil, formed during the Early Jurassic period around 195 million years ago. Discovered on the world-famous Jurassic Coast of England, its spiral ridges are preserved in fine pyritized detail, giving the fossil a natural metallic luster. Both scientifically significant and visually captivating, it is a wearable relic of deep time, framed in either sterling silver or 18k gold.
The History
The Jurassic Coast of Dorset, England, is a UNESCO World Heritage site celebrated for preserving one of the richest fossil records on Earth. Ammonites such as Promicroceras thrived in shallow seas during the dawn of the Jurassic, leaving behind their coiled shells as enduring symbols of life’s resilience and evolution.
Through the process of pyritization, the original shell material was replaced with iron pyrite, creating a fossil of remarkable metallic beauty. To wear such a piece today is to carry a fragment of Earth’s deep history — a tangible link to life nearly 200 million years ago.

The Athenian Owl pendants are awesome! We're saving the gift for a special occasion. My wife loved it, she got it and was all hushed quiet, that smile while opening and handling it for the first few minutes. It's special.
