Ammolite forms from fossilized ammonite shells found in the Bearpaw Formation of Alberta, Canada. This remains the only commercial source for gem-quality ammolite in the world.
Ammolite is among the rarest gemstones available. It forms under specific geological conditions from 70-million-year-old fossils, and gem-quality material comes from a limited geographic area in southern Alberta.
Ammolite measures 3.5 to 4.5 on the Mohs scale, so avoid contact with harder materials. Clean with a soft damp cloth and store separately from other jewelry to prevent scratches.
