Ammolite
Ammolite is an opal-like organic gemstone found along the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which are composed primarily of aragonite, the same mineral contained in nacre, just as in a shell. In 1981, ammolite was given official gemstone status.
Ammolite is celebrated globally for its naturally captivating rainbow colors and layers of vibrant iridescence. Ammolite originates from prehistoric marine fossils that date back 71 million years. Feng Shui experts believe its colorful display awakens positive energy and stimulates creativity, energy, wisdom, intellect and wealth. Wearers and collectors call ammolites "gems of enlightenment."
