Ammolite as a gem stone has some superior qualities that make it a real gem.
Ammolite Facts, Information and Description
Mined in Alberta, Canada, ammolite was recognized by the International Colored Gemstone Commission (ICGC) in 1981 as a new organic gemstone and is considered the rarest gemstone in the world.
Ammolite
Chemical composition -- Calcium carbonate.
Color -- Dark gray with brilliant iridescent flashes of green, gold, red, and sometimes blue or purple.
Appearance
Ammolite is fossilized shell material. The name should not be confused with "ammonite", which is the name of a fossilized sea creature.
Ammolite Ammolite is a gemstone create from the shell of a fossilized sea creature that existed over 65 million years ago called an ammonite. Ammolite is found exclusively in southern Alberta Canada, and occasionally in small parts of Montana.
ammolite
Ammolite (also known as korite, calcentine, or Buffalo Stone.) is a fossilized, opalized ammonite shell used as a gemstone (it is the shell of the ammonite, a fossilized marine animal, a cephalopod).
Ammolite
Ammolite is a rare and valuable opal-like organic gemstone, it is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral that makes up nacreous pearls.
Ammolite: This gem is the result of the fossilization of extinct, shelled mollusks, called ammonites.
Ammolite: (also known as Buffalo Stone, calcentine, or korite) is the fossilized shell of the ammonite, an ancient cephalopod. It can be used as a gemstone and is a gray, iridescent stone with flashes of blue, green, purple, red, or yellow.

Canada's gemstone and considered one of the rarest organic gems. Millions of years of pressure creates this beautiful gem from the fossilized remains of the ammonite shell.
Ammolite is mined in Canada and is one of nature's oldest and rarest gems. It is formed from the mineralized remains of an upper Cretaceous fossil called the Ammonite Placenticeras. No two gems will exhibit the same luminous pattern and play of color.

The nacreous layer of the aragonite fossil shells of some extinct ammonites forms an iridescent material called ammolite. Ammolite is primarily aragonite with impurities that make it iridescent and valuable as a gemstone.
Opal can be confused with glasses and some plastics. Labradorite feldspar and ammolite can be confused for opal due to their play of color.

Fracture filling, synthetics.
This phenomenon can be observed in everything from the "thin film" interference of a soap bubble, to seashell nacre, oil slicks, butterfly wings, and minerals such as ammolite, cat's eye, feldspar, labradorite and opal.
gemstones have the unique ability to display a majestic star pattern, the intriguing feline like Cat's-eye, the almost hypnotic billowing sheen of moonstone, and the playful iridescent patterns of contrasting color seen in Fire Agates and Ammolites.
Composite stones are also conceived to enhance the hardness or durability of a gem. Opal and ammolite are usually in doublets or triplets to increase durability.
