Dainty stacker rings made of sterling silver with ammonite center. Ammonites appeared 425 million years ago and were very common ocean animals throughout the age of the dinosaurs. They died out 66 million years ago. Ammonite has healing properties that are known to best represent the root chakra, while also stimulating the third-eye. These aquatic fossils are a good warrior against negativity. It's no surprise that ammonites, with their spiral shape, are symbols of change and positive motion. The spiral draws in negative energy, filtering it through the chambers and releasing fresh, positive energy.
