ammolite Facts

Ammolite is a colorful, iridescent gem created by fossilized ammonite shells!

This beautiful organic gemstone is found in Southern Alberta, Canada.

Ammonites were squid-like creatures with beak-shaped jaws.  Ammonites became extinct approximately 66 million years ago, along with the dinosaurs!

Most ammolite is green and red, while blue and violet ammolite is more rare.

There are 2 different types of ammolites, in regards to their appearance:
Fractured Ammolite - Resembles stained glass.
Sheet Ammolite - An unbroken piece of ammolite where the colors are continuous.
