Ammolite Stone Overview

Ammolite stone is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains. It is made from fossilized shells, mostly aragonite, with a microstructure inherited from their ammonite ancestors.

Ammolite can contain a variety of minerals besides aragonite, including calcite, silica, and pyrite.

It is one of only a few biogenic gemstones, the others being amber and pearl. It is a rare gemstone known for its shimmering, multicolored iridescence. It’s been said to hold the energies and vibrations of the universe.

This article will detail the properties, meanings, and uses of the Ammolite stone.

  • Variety of: Fossil
  • Wearability: Good
  • Symbols: Karma, Rebirth
  • Color: Red-Green, Mosaic-Like
  • Hardness: 4
  • Birthstone: None

What are the origins of The Ammolite Stone?

Ammolite is one of only a few biogenic gemstones, the others being amber and pearl. It is a rare gemstone known for its shimmering, multicolored iridescence. It’s been said to hold the energies and vibrations of the universe. One of the rarest jewels in the world, ammolite is solely mined for commercial purposes in Southern Alberta. The value of ammolite has increased over time due to the material’s rapidly declining supply.

Ammolite is formed from fossilized shells of the Upper Cretaceous disk-shaped ammonites; Placenticeras meeki and Placenticeras intercalare, and (less commonly) cylindrical baculites such as Baculites compressus.

Ammonites were mollusks that flourished in the seas during the Mesozoic era. In addition to coexisting with dinosaurs, they also became extinct at the end of this period.

As the ammonites died, they sank to the bottom and were covered by layers of bentonitic mud and sediment that eventually became shale. Many gem-quality ammonites are found within these concretions—their aragonite shells preserved from conversion into calcite due to the presence of siderite.

History Facts about Ammolite Stones

In 1981, the World Jewellery Confederation (CIBJO) officially designated Ammolite as a gemstone. That exact year commercial mining of Ammolite began, and in 2007 it was declared the official gem of Lethbridge, Alberta—its discovery location.

In 1967Marcel Charbonneau and Mike Berisoff became the first people to create commercial doublets of Ammolite. They later formed Ammolite Minerals Limited.

Where does the name Ammolite come from?

The name “Ammolite” comes from the spiral shape of their fossilized shells, which resemble tightly coiled rams’ horns.

Pliny the Elder (d. 79 AD near Pompeii, Italy) called fossils of these animals ammonis cornua (“horns of Ammon”) because the Egyptian god Amun—who was typically depicted wearing rams’ horns—was also known by this name in some ancient cultures.

What are some other names for Ammolite?

The fossilized ammonite remains were named snakestones in England because they resemble coiled snakes turned to stone.

Some other names for the gem are:

  • aapoak (Kainah for “small, crawling stone”)
  • Calcentine
  • Korite (given by the Alberta-based mining company Korite)

How to pronounce Ammolite?

Ammolite is pronounced as “am-muh-ligh-t” with stress on the second syllable.

How are Ammolites Stones extracted?

Commercial extraction of gemstones involves digging shallow pits and screening the excavated material for gems. The cavities are carefully examined by hand, and the commercial production is supplemented by individuals who sell their surface-picked findings to Korite International and other producers.

Approximately 50% of the Ammolite stones mined are suitable for jewelry. However, Korite International, which mines most of the world’s supply, produces over 90% of it.

Most ammolite stones do not have enough thickness to be used on their own, so they are given some backing that should not exceed more than 1.5mm in thickness. This is done so that gem cutters can use the gemstone properly. The backing is typically made from shale or synthetic spinel.

If they are given a more stable backing, they will be kept in a free-form shape.

Where can you find The Ammolite Stone?

The Ammolite gemstone, made from the fossilized shells of ammonites, has only been found in significant deposits within the Bearpaw Formation that extends from Alberta to Saskatchewan in Canada and south to Montana in the United States of America.

However, small deposits have been found in a few countries, including:

  • Austria: Kholergraben
  • Canada: Lethbridge
  • Madagascar: Ambato-Boeni

What is the typical appearance of An Ammolite Stone?

It is common for fine specimens to show an iridescent opal-like play of color; all the spectral colors are possible, though green and red shades predominate.

The microstructure of its aragonite causes the colors in Ammolite stones: unlike most other gems, which get their colors from light absorption, Iridescent coloration is produced when thin platelets that makeup Aragonite stack to create interference; this process occurs only with Ammolite stones.

Thicker layers produce a more significant number of red and green hues; thinner ones create more blues and violets. Reds are the most common colors, owing to the fragility of thinner layers that give rise to blue pigments. When first mined, the colors in raw fossils are not especially dramatic; it takes polishing and possibly other treatments to reveal their full potential.

The Ammolite stone is rarely found in nature without its shale or clay host matrix, which can range from gray to brown. As a result, frost shattering—wherein the delicate ammolite cracks and splits due to exposure and pressure by sedimentary deposits on top of it—is common.

The cracks give it a tessellated appearance, sometimes called “dragon skin” or “stained glass window.” It may be smooth or rippled if mined from deeper deposits.

Sometimes, a complete ammonite shell is recovered with its structure well-preserved: fine and convoluted lines delineate the outer portions of the chambers; overall, the ammonite shell has a shape similar to that of a nautilus.

Ammolite Cost and Value

Ammolite Stone Cost and Value

Ammolite’s cost is influenced by several factors, including clarity, carat weight, and cut. Jewelry made from this stone can range from $50 to $500. The cost of a real ammonite fossil can be very high, with some pieces costing as much as $10. A large Ammolite with beautiful iridescence may go for up to $50,000. The factors affecting the cost of Ammolite are:

  • Size: Price increases drastically with an increase in size as more giant fossils are rarer and harder to find.
  • Quality: Quality is determined by the intactness and clarity of the fossil. Those with the least fractures or inclusions are worth more. The brightness and iridescence are also considered determiners of quality.
  • Color: The color of the Ammolite influences its value as well. The more intense these colors are, the higher the fossil’s value. 
  • Rotational Range: There will be no vibrant or intense colors that occur through the rotation of 360 degrees in some materials. A 360-degree rotation through the brilliant color occurs in a high-grade gemstone.
  • Sources: It is only in the Bearpaw formation that Ammolite can be found. The best quality gems are on the eastern slope of high-energy river systems where Southern Albert’s rocky mountains lie.

Some other factors influencing the cost are iridescence and chromatic shift.

What Materials are used To Imitate Ammolite Stones?

Ammolite is not easily imitated; however, some materials have a passing resemblance that may trick the unsuspecting buyer. These include:

  • Labradorite (also known as spectrolite), an iridescent feldspar that may also be of Canadian origin; and broad-flash black opal. Neither are convincing substitutes, and the latter is actually of more excellent value than Ammolite.
  • Solcum Stone is a common glass-based imitation of opal. A Slocum stone’s body is transparent to translucent from certain angles, whereas Ammolite is entirely opaque.
  • Shell-based marbles, this group includes Lumachella or “fire marble,” a similarly iridescent marble composed of fossilized clam and snail shells. The iridescence of Lumachella is fragmentary and not nearly as brilliant as that of Ammolite.
  • The iridescent body of the Abalone (or paua; genus Haliotis) is one last possible imitation. The luster of the abalone shell is silky rather than the near vitreous sheen of polished Ammolite, and their colors do not match closely. However, some abalone shell has been dyed and given a transparent cap of synthetic quartz—in the same fashion as Ammolite. These doublets are perhaps the most deceptive; they’ve also been used to imitate opal.
