Natural Black Orthoceras, 925 Sterling Silver pendant. The stone fossil is 21.48 cts and weights 8.26 grams. The Orthoceras is a genus of extinct nautiloid cephalopod. Its name is derived from the words “straight horn”, referring to it’s long, conical shell. These creatures roamed the seas during the Ordovician Period (485 million - 443 million years ago). In meditation, it connects to ancient earth. In healing, fossils may be helpful in assisting with aliments of the bones, skeletal system, hands and feet. Please see my listing for a matching ring and earrings to go with this pendant. I hand picked all three items to be a matched set.
