Ammonites became extinct 65 millions years ago along with the dinosaurs so these fossilized shells are 65-400 million years old! When ammonites are found in clays their original mother-of-pearl coating is often preserved, you can see this in the back shot.
These beautiful ammonite fossils are 1 1/4″ long and set in solid .925 sterling silver. They hang from my own handmade solid sterling silver ear wires. The last photo shows the transparency of the ammonite fossil.
Whenever I wear mine I get tons of compliments on how unusual and beautiful they are. Such beauty in nature!
