Ammonite fossil earrings set in sterling silver. The name ammonite is derived from the name of the Egyptian god Ammon. These fossils are from sea creatures that lived in the Devonian period some 395-345 million years ago when oceans covered the land masses. Every pair looks a little different as no two were ever the same as well as all being a little different in size. Sizes will be a bit over 1/2 inch up to 3/4. We are happy to text you a picture of the exact ones you will be receiving, but you need to request that on your order.
