(Ammolite Information) A true treasure of nature, ammolite is the rarest of all gemstones and exclusively Canadian. Ammolite is an 'opal like', organic gemstone that is formed from fossilized, extinct mollusks called Ammonites. Ammonites were a squid-like marine animal and existed through out the Paleozoic Era until the end of the Crustaceous Era, when they abruptly became extinct. Ammonites were abundant in all of the oceans and their fossils are found all over the world but it is only those extracted from the Eastern slopes of the Rocky Mountains in Southern Alberta, Canada that boast the captivating, iridescent colours mirroring the brilliance and flashing dance of the Northern Lights. Only 5% of the ammonite fossils in Alberta exhibit 'Ammolite' colours and of these stones only a small portion are considered to be of gem quality. Every Ammolite is unique, showing it own beautiful and intricate patterns, colour combinations and brilliance like a personal signature.
