The gemstone is likely a piece of ammolite, a rare and valuable gemstone that is found in only a few locations around the world. Ammolite is a type of opal that is formed from the fossilized shells of ammonites, an extinct group of marine animals. The gemstone is prized for its unique and iridescent colors, which are caused by the way light interacts with the microscopic structure of the shell.
