Ammolite history

Ammolite comes from the fossilized shells of the cephalopod mullosk Placentriceras Meeki and Placenticeras Intercalare. These mollusks thrived in tropical seas until becoming extinct at the end of the Mesozoic era.

These Ammonites were inhabitants of a prehistoric subtropical sea called the Bearpaw Sea or Western Interior Seaway that extends along Alberta and Saskatchewan also reaching into the Montana in the USA.

Ammolite is an organic gemstone, like Amber and Pearls and Ivory. While different types of Ammonite fossils can be found throughout the world; Ammolite can only be found in a small portion of North America. Ammolite has been designated the official gemstone of Alberta and Lethbridge. It is one of the rarest known gemstones in the world.
