What is Ammolite? Ammolite is one of the last precious gems to have been discovered, and was granted official gemstone status in 1981 by the International Commission of Coloured Gemstone. Ammolite is formed from an ancient marine creature called an Ammonite. Ammonites survived until the end of the Cretaceous period, 65 million years ago, in a sea that covered what is now Alberta and Montana. Although sources of ammonite exist in other locations around the globe, it is only in one isolated region of Southern Alberta, Canada, that this deposit produces the gemstone Ammolite. Seventy-one million years of tectonic pressure, heat and mineralization have resulted in the formation of this geological wonder. It is the rarity of Ammolite, along with its captivatingly beautiful colours that make is so unique and creates such stunning jewellery.
The colour of Ammolite The colour present in Ammolite is caused by light interference during refraction into the many layers of the gemstone. Each color in Ammolite represents a different layer of the gem material. Depending on the number of fine layers in the rough, everything from one colour to the full visible spectrum will be displayed. Since the play of light varies, every Ammolite gem shows a unique array of color.
Availability The supply of Ammolite is extremely limited and with only one area for mining, Ammolite truly is one of nature's rarest gems. Since 1983 Korite’s eco-friendly Ammolite mine has produced over 90% of the world’s supply of this incredibly rare gem.
