About Opal Belemnites

Belemnites were ancient marine creatures — relatives of modern squid and cuttlefish — that lived during the Jurassic and Cretaceous periods, approximately 135 million years ago. When they died, their hard internal rostrums (the bullet-shaped guard) were buried in sediment and, over millions of years, replaced by precious opal. The result is one of nature's most extraordinary fossils: a genuine prehistoric creature preserved in gemstone.

These specimens are highly sought after by opal collectors, fossil enthusiasts, and jewellers alike. High-quality belemnites make exceptional pendants and statement pieces.
