Ammonite Fossil Cut and Polished Pair - 40mm

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.

Specimen Details

• Type: Ammonite fossil, cut into a pair of halves
• Size: Approximately 40 mm
• Finish: Polished interior faces with visible spiral chambers; the outer surfaces retain a more natural texture
• Appearance: Earthy brown, amber and grey tones with pale chamber outlines; subtle iridescence is visible on parts of the outer shell

Natural fossil markings, uneven areas and colour differences are part of this pair’s character. The coin shown in the photographs is for scale only and is not included.
