Ammolite is a rare and valuable  organic gemstone found  in southeastern Alberta taken from the shells of  fossilized Ammonites, composed primarily of aragonite. This is the same mineral that makes up nacreous pearls. It is one of few biogenic gemstones; others include amber and pearl. In 1981, Ammolite was given official gemstone status by the World Jewelry Confederation. In the same year commercial mining of Ammolite began. 

Ammolite comes in the full spectrum of colours: red, orange, yellow, green, blue, indigo and violet. The quickly depleting world supply of Ammolite makes it a unique and memorable purchase. Ammolite is also known as Alberta’s Gemstone.

Ammolite’s iridescent colours glow with the beauty of a rainbow. Millions of years of tectonic pressure, glacial temperatures and minerals created this beautiful gem from the fossilized remains of the Ammonite shell. A glittering addition to any jewelry collection, Ammolite’s luminous qualities rival the famous black opal for colours and fire.

Each Ammolite gem is unique in brilliance, colours and pattern. Photos on the website capture only one mesmerizing facet of this spectrochromatic gem.  

Ammolite, like all gem stones, should be treated gently: not soaked in water, not exposed to harsh chemicals or extreme temperatures, and cleaned only with a soft cloth.
