In 1981, ammolite was given official gemstone status by the World Jewellery Confederation, the same year commercial mining of ammolite began. This structure allows the ammolite to show the most brilliant flash while protecting it in a setting durable enough for everyday jewelry wear.Īmmolite is one of few biogenic gemstones others include amber and pearl. On top, there's usually a calibrated cap of optical quartz or synthetic spinel. They're backed by the original shale of the fossil.ĭoublets are freeform cabochons bonded to a backing.Īmmolite triplets are usually constructed on a dark gray wafer of natural shale below a thin layer of ammolite. With a wide range of dazzling colors and patterns, this organic gemstone is highly desired for freeform natural cabochons and assembled jewelry pieces.Īmmolite “naturals” are freeform cabochons with a non-coated hand finish. At work, Ammonite brings long lasting success and stability to new or high-tech firms.Īmmolite is cut from the fossilized shells of extinct ammonites and found only in the Bearpaw Formation in Alberta, Canada. They also create an organised home and increase domestic harmony. As it grew, it added newer and larger chambers to the open end of the coil.Īmmonite will help bring tradition and character to a newly built house. Only the last and largest chamber, the body chamber, was occupied by the living animal at any given moment. Ammonite gemstone series#It contains a series of progressively larger chambers, called camerae that are divided by thin walls called septa. It is highly iridescent, frequently exhibiting red, green and orange. Other less-frequently used trade names for Ammolite are 'Calcenite' and 'Korite.' It is also known simply as 'ammonite shell.' Ammolite is a rare material. Ammonites are similar in appearance to a ram's horn.Īmmonite can be distinguished their shape which looks like a coil with a wide mouth. The chambered part of the ammonite shell is called a phragmocone. Ammolite is a rare, opal-like, gemstone composed of the shells of fossil ammonites. Ammolite is a trade name given to a thin iridescent aragonite shell material that is found on two species of extinct ammonite fossils ( Placenticeras meeki and Placenticeras intercalare ). The word ammonite is derived from Ammon, an Egyptian god who took the form of a ram. These fossils are known as "shaligram shila". They are mostly collected in Nepal, from the bed of the River Gandaki where it cuts through Jurassic sediments. In India, ammonite fossils are identified with the god Vishnu and are used in various ceremonies. It is said that the original discus used by the ancient Greeks in their Olympics was in fact a fossilised ammonite. Because of their rapid evolution and wide distribution, ammonite fossils provide a useful tool for indexing and dating rocks. Ammonites inhabited the world’s oceans and now appear as fossils in marine rocks. The extinction of ammonites coincided with the extinction of dinosaurs. Now extinct, the ammonite mollusc was a shelled cephalopod.
