The ammolite gemstone used in Sagacia’s Ammolite Earring is mined from the Bearpaw Formation that stretches between Canada and the United States of America. This particular location goes through Alberta, Saskatchewan, and Montana. Although you will find ammonite fossils all over the world, only specific geological conditions create gem-grade ammolite which are limited to certain areas. Some people who sell ammolite jewelry such as ammolite earrings source this gemstone from England and Madagascar, but the main problem with this particular grade of ammolite is, that it is more fragile, and it has a dull coloring.
