Seventy-five million year old mother of pearl from the shell of an ammonite. Move the sample backwards and forwards under a light. The colours flicker and change. This is a perfect choice for a piece of high end jewellery, or a craft project.
Ammonite shells were made of three layers of aragonite, which served different functions and are structurally different. The middle layer was nacre or mother of pearl. This layer can preserve well, and can be found on ammonite fossils throughout the world.
The word ammolite is a brand name and can only be used to describe nacre from ammonites from Alberta, Canada. It is the only fossil which is also recognised as a gemstone by the GIA.
