More About the Ammonite/Ammolite Fossil Stone and the Grading of the stone "The term ‘ammonite’ refers to an extinct group of mollusks. These creatures, along with the dinosaurs, died out at the end of the Cretaceous Period around 65 million years ago. When ammonites died, they were deposited at the bottom of the ocean and covered with sediment. After being buried for millions of years, the remains of these marine organisms fossilized and left behind shells which are found throughout the world. In some parts of Southern Alberta, the shell of the ammonite creature has an outer layer of beautiful colour. This colour is a gemstone called ‘ammolite’ and was created as a result of the geological and mineralogical processes that occurred in these areas." "Grading the stone is based on the scope of colors that the Ammolite shows and the vividness of these colors. To achieve the AA or A + grade status, the ammolite gemstone must meet certain criteria. It has to have at least three colours: one from the blue, green and red family. These grades are a step above showing more rotational colors and unique appearances."
