Pyritized Ammonite and Diamond Necklace

About the Piece

This is one of the most unique necklaces I have created to date. I came across this pyritized Ammonite negative at the Tucson Gem Show and could not pass it up. This highly detailed piece is actually the negative impression of an Ammonite fossil that became pyritized over the years. It is set in 14k yellow gold, and is accented with gold accents and a diamond. This piece has a sterling silver backplate and hangs from a 14k gold cable chain.

A Note on this Stone

This is an ammonite impression fossil collected in Germany. It is from the Jurassic, Pliensbachian stage or approximately 185 million years old. Ammonites are extinct mollusks that resemble a squid with a shell. These cephalopod creatures had eyes, tentacles, and spiral shells. They were one of the dominant life forms in the ocean during the Mesozoic era but went extinct along with the dinosaurs 65 million years ago.
