Ammolite is a rare and valuable stone of organic origin, which is obtained from fossilized shells of ammonite (extinct animal in the Upper Cretaceous).
Due to its structure, consisting primarily on thin sheets stacked of aragonite, ammolite gem displays an IRIDESCENT phenomenon. Thicker plates of aragonite are red and greenish, the most thin and fragile are the blue and violet.
Ammolite displays a beautiful play of colors, the most common are green and red.
The more colors and more iridescence and brightness the ammolite has, the more valuable the stone will be.
The Ammolite Gem is usually cut in freeform cabochon (doublets or triplets).
