The history of the Ammolite goes back some 70-75 million years to the Cretaceous period, when the Rocky Mountains were formed. To the east of this was a huge sea, the Western Interior Seaway. This sea was colonized by many creatures, including ammonites. These sank to the bottom of the sea after their death and were covered by the impermeable volcanic ash from the forming Rocky Mountains and fossilized there.
Ammolite is the trade name for the gemstone quality of a colorful, iridescent fossil shell of two ammonites: Placenticeras meeki and Placenticeras intercalare.
The gemstone consists of the finest aragonite platelets, which produce the bright colors through interference of light. Good Ammolite shows a play of colors that is in no way inferior to the noblest opal.
