Ammolite: Gemstone and Jewelry


Ammolite is one of the most fascinating gemstones in the world. It is an organic gemstone that is primarily composed of fossilized ammonite shell, which means it is a rare and precious gemstone. Ammolite is a favorite among many jewelry enthusiasts and gem collectors because of its unique beauty, rarity, and interesting geological history. In this article, we will explore the fascinating world of ammolite and its jewelry, including its geological history, mining, properties, uses, and significance in various cultures.



Geological History: 

Ammolite is actually the fossilized shell of an extinct marine mollusk called ammonite, which lived 70 to 75 million years ago during the Cretaceous period. The ammonite was a cephalopod with a spiral shell that grew up to 1.8 meters (6 feet) in diameter. It lived in the sea and was related to modern-day squid and octopus. Ammonites became extinct about 65 million years ago after a catastrophic event that wiped out the dinosaurs and many other species, including ammonites.

The fossilization process of ammonite shells is a complex one that involves the replacement of the original organic material with minerals, mostly aragonite, which is a form of calcium carbonate. The minerals are deposited in the chambers of the shell, creating different colors and patterns that make each ammolite gemstone unique. Ammolite was first discovered in the 1950s in the Bearpaw Formation of the Rocky Mountains in Alberta, Canada.

The area was once a vast sea that covered what is now Canada and the United States. The fossilized ammonite shells were buried under layers of mud and sediment, which preserved them for millions of years. Today, the area is one of the few known sources of ammolite gemstones.




Ammolite is a relatively rare gemstone that can only be found in a few places in the world. The largest source of ammolite is the Bearpaw Formation in Alberta, Canada. The area is known for its high-quality ammolite with vibrant colors and beautiful patterns. Other sources of ammolite include Madagascar, Russia, and the United States, although the quality of the gemstones from these sources is often lower than those from Canada.

Mining ammolite is a delicate process that requires skill and expertise. The ammonite shells are fragile and can easily break during mining and extraction. To prevent damage, the shells must be carefully extracted from the ground using specialized tools and techniques. Once the shells are extracted, they are cleaned and polished to reveal the beautiful colors and patterns inside.




Ammolite is an organic gemstone with unique physical and optical properties. It has a hardness of 3.5 to 4 on the Mohs scale, which makes it relatively soft compared to other gemstones like diamonds and sapphires. As a result, it requires gentle care and should be protected from scratches and impacts.

One of the most distinctive properties of ammolite is its iridescence. The gemstone exhibits a play of colors that changes depending on the angle of the light and the viewing angle. The colors range from red, orange, yellow, green, blue, and purple, and are often arranged in intricate patterns that resemble the scales of a fish or the wings of a butterfly. The iridescence is caused by the diffraction of light as it passes through the layers of aragonite in the shell. This property makes ammolite a highly sought-after gemstone for jewelry.




Ammolite is primarily used in jewelry, where it is crafted into earrings, necklaces, pendants, bracelets, and rings. Its unique beauty and rarity make it a popular choice among jewelry enthusiasts and collectors. Ammolite jewelry is often designed to showcase the gemstone's iridescence and patterns, making it a statement piece that can be worn on special occasions.

Apart from jewelry, ammolite is also used in decorative objects like vases, sculptures, and wall art. The gemstone's vibrant colors and patterns make it a popular choice for interior designers and art collectors who want to add a touch of nature to their spaces.



Significance in Cultures: 

Ammolite has a significant cultural value in several cultures around the world. In the Blackfoot culture of Alberta, Canada, ammolite is considered a sacred stone that symbolizes the buffalo, which was a vital source of food, clothing, and shelter for the Blackfoot people. The stone is used in traditional ceremonies and is believed to have healing properties that can protect against negative energy and promote spiritual growth.

In Chinese culture, ammolite is known as the seven-color prosperity stone and is said to bring wealth, health, and happiness to its wearer. The gemstone is often worn as a Feng Shui ornament or placed in a wealth corner of the home to attract good fortune.




Ammolite is a unique and fascinating gemstone that is prized for its iridescence, rarity, and interesting geological history. Its properties and uses make it a popular choice for jewelry enthusiasts and collectors, as well as interior designers and art collectors. The gemstone's cultural significance in various cultures adds to its value and appeal, making it a truly special gemstone that deserves more attention and appreciation. With its vibrant colors, intricate patterns, and fascinating history, ammolite is a gemstone that is sure to captivate anyone who encounters it.
