This pendant features a genuine Promicroceras ammonite, formed during the Early Jurassic period—approximately 195 million years ago—and discovered along the famed Jurassic Coast of England. Preserved in dazzling pyritized detail, its natural spiral and ridges shimmer with a metallic luster, a testament to deep time. Now framed in solid 18k gold, this fossil has been transformed into a wearable relic of Earth’s ancient seas. It is the exact pendant in the first picture, the piece with red arrow pointing at it (in the second), and the one on the right (in the third)
The History
Ammonites, extinct relatives of modern squids and octopuses, once thrived in the oceans of the Jurassic. Their spiraling shells, preserved in stone, became enduring symbols of evolution and natural resilience. The Dorset coast where this specimen was found is a UNESCO World Heritage Site, celebrated for its unrivaled fossil record. Through pyritization—the replacement of shell material with iron pyrite—this ammonite was transformed into a golden-toned fossil of striking beauty. To wear it is to carry a fragment of Earth’s story, sealed for nearly 200 million years.

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.
