Gifted to friend Ammolite pendant

Gorgeous ammolite pendant in shades of iridescent green, teal, with a few hints of orange, red. and purple. Teardrop shaped and about two inches long. It is a gemstone that is the fossilized shell of an ammonite, a sea creature that lives millions of years ago. This was has some subtle suture markings (the swirly looking parts), which are a natural pattern within the shells and are fairly rare. Never worn, NWOT. The last photo is a comparison of all the ammolite I have listed, this listing is just for one of them.
