40mm Cut and Polished Ammonite Pair
Two matching halves of an ammonite fossil, cut open to reveal the coiled chambers inside. The polished faces show a striking spiral of warm brown, amber and grey, outlined by pale chamber walls. Place the halves side by side on a shelf or desk to enjoy the mirrored pattern, or share one with a fellow fossil enthusiast.
Geology & Formation
Ammonites were marine molluscs whose coiled shells were divided into chambers. As the shell was buried and fossilised, its internal structure was preserved, creating the intricate pattern revealed by cutting and polishing.
