The classification of ammonoids is based in part on the ornamentation and structure of the septa comprising their shells’ gas chambers by these and other characteristics subclass Ammonoidea is divided into three orders and eight known suborders. Originating from within the bactritoid nautiloids, the ammonoid cephalopods first appeared in the Devonian period (over 400 million years ago) and became extinct at the close of the Cretaceous period, along with the dinosaurs. Mohs Hardness of 3.5-5 with a trigonal crystal structure (of the outer layer) What are the Scientific Properties of Ammolite? ![]() Organic materials that have been mineralized to gemstones include: Dino Bone (Gem Bone, Gembone) Petrified Wood, Fossils such as Ammolilte and Ammonite during the mineral infilling the organic structure is preserved therefore it remains an organic material, and thus an Organic Gem. Organic materials considered gemstones include but are not limited to: Amber, Bone, Coral, Ivory, Pearls, Mother of Pearl, Abaone as well as meteorites such as Moldavite While many minerals are considered gemstones, there are also a number of materials that have been infused, infilled or partially replaced by organic materials as well as natural organisms that have been mineralized then used and considered valuable ‘gems’ throughout all our time. More recently they have been called Snakestones as well as St. In the Middle Ages Ammolite was known as Draconites due to their bright colors and what was then considered a bizarre appearance, they were thought be ‘stones’ stolen from a dragon’s head. ![]() This iridescence would not have been visible during the animal’s life, it is simply the coating or replacing of the shell by the opal. Ammolite was given the official gemstone status in 1981 by the World Jewelry Confederation. ![]() The ‘opalilzed’ or iridescent Ammolites are comprised primarily of Aragonite, which is the same mineral that creates a nacreous Pearl. These are the fossilized shells of the Ammonite the opalization is formed by minerals filling in the sedimentary rocks or veins in rocks it has also been known to replace organic materials in fossils, wood and shells, even bone. However, in stricter usage the term Ammonite is reserved for members of suborder Ammonitina (or sometimes even order Ammonitida).Īmmolite on the other hand, is an opalized version of the Ammonite found primarily along the eastern side of the Rocky Mountains from the US and Canada. The words ammonite and ammonoid are both used quite loosely in common parlance to refer to any member of subclass Ammonoidea. It must also not to be confused with a Nautilus, which has a similar shape but an entirely separate make up.Īmmonites are an extinct group of marine animals. Pliny the Elder (circa 79 AD) referenced this name for the Egyptian God Ammon – who was typically depicted wearing rams horns. It’s name was inspired by the spiral shaped of the fossilized shells, being that of a tightly coiled ram’s horn. Ammonite is not a gemstone, but rather a fossil. There has been much confusion between Ammonite and Ammolite in the metaphysical world, often falling on the side of describing the Ammolite and not the Ammonite. ![]() Ammolite, the Stone of Prosperity & Good Fortune:
