Wear a piece of ancient history with this ammonite fossil pendant necklace! This fossilized ammonite has been halved to reveal the spiral pattern and agatized inner chambers. This gorgeously dainty specimen forms a perfect spiral measuring approximately 14mm across by 17mm high. The surface of the fossil is polished to a lovely shine highlighting the intricate organic pattern of rich earthy butterscotch and amber hues. The antique brass pendant bail was bonded to the back of the fossil using E6000 industrial strength cement. Fossil pendant hangs from a 20 inch long antique brass rope link chain securing with a lobsterclaw clasp.
