Iridescent Green, Purple and Blue Ammolite. Ammolite is an officially recognized gemstone that forms from the fossilization of the nacre (mother of pearl) of an ammonite in only one place on earth, the late cretaceous (70 to 80 million years ago) Bearpaw Formation of Alberta, Canada. Ammolite forms by pressure and the mineralization process that requires many millions of years and just the right condition. Ammolite was certified as a gemstone in 1981 by the World Jewelry Confederation. Ammonites are extinct mollusks that are related to modern day squid and octopus. They became extinct with the dinosaurs some 65 million years ago. This large 4.5X4X3 inch section of a sizeable ammonite has iridescent ammolite on two of its sides. The sparkling iridescent ammolite consists of green, rare purple and even some of the very rare blue color. Blue is the rarest of all of the Ammolite colors. Complete ammonites with such excellent Ammolite colors sell for at least $20,000.
Estimated Value $750 - 1,000.
