Genuine ammonite fossil with a sterling silver bail and chain. This gorgeous pendant necklace specimen makes beautiful geek jewellery! A really nice cephalopod fossil, hailing from Morocco. While some people call these nautilus fossils, an ammonite is more closely related with modern squid. This creature is brown, the common hue for ammonites. The pendant stone is over 1 1/2 inches (4 cm) long, & around 1 1/3 inches (3.3 cm) across. I've added a sterling silver chain 18 inches (51 cm) long, but you can also choose a different length.
