Ammolite was discovered by the Blackfoot Indians in the Canadian Rocky Mountains who named it Buffalo stone. A Blackfoot woman discovered the stone when looking for firewood. It was a harsh winter and there were few buffalo and her people were starving. She heard singing and was drawn to an unusual rock under a cottonwood tree. The ammolite stone told her it was powerful medicine and to take it back to her tribe and it would provide bison for her tribe to eat. The next morning a huge herd of buffalo was seen right outside of their camp. The ammolite stone was used in bison hunting ceremonies . It was wrapped in a medicine bundle of buffalo hide.This buffalo stone was called Iniskim. Today we call it Ammolite.
More than 70 million years ago a hard shelled squid like marine animal roamed the seas until they suddenly became extinct. When the inland sea receded, ammonites were found in the Bearpaw shale near Lethbridge, Alberta Canada. The shells were layered then covered with silt and volcanic ash and crushed and compacted. With eons of elemental movement, tectonic pressure and intense heat, ammolite was born.
Ammolite is a fossil of an ammonite. It is sometimes
referred to as "Grandmother of Pearl". It has only been a recognized gemstone since 1981. It is only found in a small area of Southern Alberta and obviously no more is being formed, which makes this beautiful gem very rare. It is also used in Feng Shui promoting prosperity and healing.
