This unique ring is not black opal, though it looks somewhat like it and has been compared to it. This flashing stone is called ammolite, and is a very rare gemstone. The only mine in the world is in Canada. Over 70 million years of tectonic pressure created this brilliant gemstone from the fossilized shell of a prehistoric ammonite. Ammolite. It was first discovered by the Blackfoot Indians in an area bordering the Canadian Rocky mountains. Called "Iniskim" or "the buffalo stone", it was believed to be a powerful medicine possessing healing properties. Today, the wearer of the ammolite gem may find negative energy turning into positive, while becoming more open and generous. I were only able to get a few of these lovely ammolite rings, and cannot get any more. The ring that you see in the photo is the actual ring you will receive. There is no way the camera can do justice to this beautiful, iridescent stone! It is even prettier in person than it is in the photo. The camera is not picking up the flashing reds, oranges and greens. You'll be thrilled when you see it on your finger.
