Sterling Silver 925 - Ammonite Fossil Ring

According to the Natural History Museum; the ammonite died out about 66 million years ago. These were ocean-dwelling mulluscs. This ammonite fossil is set in 925 stamped sterling silver. A beautiful statement piece. I am letting it go because it is too small for me now. The small indent in the pictures 6 & 7 is not a flaw. This is a natural and common feature of some ammonite's.
