Ammonites Pyrite replaced cut polished, Half.
Single Ammonites cut in half to show calcite filled internal chambers and Pyrite replaced shell.
Ammonites are extinct cephalopods related to modern squids and octopuses. They had spiral shells, tentacles and would have looked similar to the modern nautilus despite not being closely related. Ammonites first appeared in the fossil record about 240 million years ago. They barely survived several major extinction events before finally disappearing 65 million years ago, at the end of the Cretaceous. Ammonite shells traditionally preserve well and are relatively common fossils.

Despite lasting as long as the ammonite had to for fossilization and discovery, ammonites aren't particularly durable with a Mohs hardness of about 4. Only gentle cleaning methods of lukewarm water and mild soap are recommended. Dry the fossil with a soft cloth not impregnated with other cleaning agents. Store ammonites and ammonite jewelry away from harder materials in its own tray with a velveteen insert or a soft, velvet bag. If participating in rigorous physical activity, remove ammonite jewelry beforehand.
