Natural Ammonite Slice 24.2g 48.8mm

A transverse cross-section through an ammonite, cut and polished to expose the internal chamber structure - a full spiral of broad chambers filled with translucent druzy quartz crystals, divided by dark brown septum walls. The geode-like crystal-filled interiors contrast dramatically with the rough dark outer shell edge at 48.8mm across.

Sliced ammonites reveal the internal geometry completely hidden in whole specimens - the sealed chambers, each with its natural quartz crystal fill, show the original living architecture of this Jurassic cephalopod. Natural ammonite cross-section from China, display specimen. Polished ammonite slice, druzy quartz chambers, Jurassic fossil, crystal fossil specimen.
