Here is a astonishingly brilliant specimen of iridescent AMMOLITE, from the Korite Mine, Bear Paw Formation, Lethbridge, Alberta, Canada. Ammolite is a natural gem type of fossilized ammonite (Placenteras meeki), which is a coiled, chambered fossil mollusk shells. It's about 71 million years old (Late Cretaceous period). Because of its very bright colors, ammolite is a popular stone for jewelry. The color in ammolite is caused by light interference during refraction into the multiple layers of the fossil, with each layer representing a different layer. Ammolite's quality is rated by the brightness of the colors and how many colors are present. Whenever I show a customer ammolite, the response is typically a quick intake of breath, then an amazed, "WOW!" By the way, we guarantee 100% that you'll be that amazed when you open the package!
Virtually all ammolite on the market has been stabilized. This is because natural ammolite is micaceous, so it cleaves into thin flakes like mica. To prevent this from happening, ammolite is stabilized by forcing epoxy into the micaceous layers under pressure, creating a stable stone that can be made into jewelry. Stabilization is an accepted treatment that has no negative impact on the gem.
