Know a Little Bit About Ammolite

If you like gemstones with provenance, then you’re going to love ammolite - iridescent fossilized ammonite shells found in Southern Alberta, Canada.

When the earth had only one continent with no forests or mammals, schools of ammonites hunted in the Tethys Ocean. Squid-like creatures, ammonites ate what they could catch with their sharp, beak-like jaws, which were buried in a ring of tentacles. 

Ammonites suffered the same fate as the dinosaurs – they became extinct about 66 million years ago. An asteroid striking the earth and the cooling climate likely caused their demise.


As countless millennia passed, two species of ammonites – Placenticeras meeki and P. intercalare – slowly turned into stunningly colored fossils called Ammolite.

Their brilliant colors enchanted Native Americans, who wore them to bring good luck while hunting buffalo. 

Most Ammolite is green and red. Blue and violet Ammolite is more unusual, and typically more valuable.

These years, high demand from Hong Kong and Japan caused the price of Ammolite to increase very fast! People loved this colorful gemstone, and Fengshui Culture also played an important role in demands. Colorful Ammolite will bring good luck to people based on Metaphysics and Numerology. 

In Japan, after the Emperor wore the Ammolite Ring in his wedding, Japanese people believed Ammolite represented 70 million years of love if worn as a ring when married. It is a lucky stone! Since then, high demand for Ammolite continued for young people when they got married. They must and have to have one!

Ammolite is described as either fractured or sheet. Fractured Ammolite resembles stained glass; sheet Ammolite is an unbroken piece where the colors are continuous. Evocative names are used to describe its diversity of appearance: dragon skin (patterns resembling scales), cobblestone (patterns resembling a cobblestone road), moonglow (luminescent with few lines or fractures), and paint brush (looks like strokes of paint).

Sheet Ammolite is typically impregnated with a polymer to stabilize its thin surface layer.

Because the layers are thin, Ammolite is almost always assembled into a doublet or triplet. Ammolite is often backed with a material like shale, black onyx, or glass to form a doublet.

Sometimes, a top layer of synthetic spinel or quartz is added to form a triplet.

Ammolite is often fashioned into pendants, brooches, earrings, and sometimes sold as display art. It is not a hard stone (3.5 on the Mohs scale), which means it can scratch easily. Heat and chemicals like acid, perfume, and hairspray, can also damage it. It is highly recommended that you use only a damp, soft, non-abrasive cloth to clean it.
