Ammolite History, Meaning, Healing Properties, Facts, Benefits, and Uses Ammolite is one of the most rare gemstones found on earth. This unique gemstone is famous worldwide for the vibrant colors it shows. The ammolite gemstone is formed out of the fossilized remnants of ammonites (which are nothing but extinct marine mollusks).
