Some of the most beautiful jewels in the world are classified as organic gemstones. As the name implies, these gemstones come from living organisms, as opposed to minerals. The most common examples are amber and pearls. Another strikingly beautiful example of an organic gemstone is Ammolite. Ammolite is a mined primarily in Alberta, Canada. It is made from the fossilized shells of ammonite, which resemble a nautilus. Ammolite is famous for its intense colors in the red and green shades. These iridescent shades are produced when light refracts off of the different levels of the ammolite stone. Because ammolite in its natural state is relatively soft, most stones used in jewelry are capped with a transparent crystal to provide protection to the delicate stone. Ammolite's value is derived not only from its beauty, but also its rarity. Currently only a small area along the Canadian Rocky Mountains produces significant quantities of gem-grade ammolite.
