Custom Order — 195 Million Years in the Making | Promicroceras Ammonite Pendant #1 (Approx. 3 weeks)
Early Jurassic Promicroceras Ammonite Fossil Pendant | c. 195 Million Years Old
Formed during the Early Jurassic period, this genuine Promicroceras ammonite was discovered on the world-renowned Jurassic Coast of England, near Charmouth Beach. Its spiral ridges are preserved in exceptional pyritized detail, giving it a natural metallic luster that has endured for nearly 200 million years.
This fossil will be transformed into a custom pendant in your choice of solid 18k gold or sterling silver, with either a hand-crafted bezel that follows the fossil’s natural contours or a minimal prong mount that maximizes visibility of its ancient form.

Mostly from reputable ancient coin auctions in Europe and the USA, plus private collections.
Do you ship internationally?
Yes, we proudly ship worldwide. Shipping options and times vary by country — you’ll see available methods at checkout.
