Semi-Black Australian Opal Belemnite Fossil 17.19cts – Queensland, Australia

A stunning semi-black opalized belemnite fossil, professionally polished to reveal vivid colour play against a dark body tone. The dark background makes the colours pop with exceptional brilliance — a highly prized characteristic in Australian opal. At 35mm long, this is a substantial specimen that would make a gorgeous pendant once set. A genuine piece of prehistoric natural history, over 100 million years old.

Belemnites were marine animals closely related to modern squid and cuttlefish. They had a squid-like body with a hard internal skeleton — the bullet-shaped rostrum — which is the part preserved as fossil. They lived during the Jurassic and Cretaceous periods and became extinct around the same time as the dinosaurs.
