Hand-formed brass cuff accented with two solid brass castings of ammonite shells. Slightly adjustable to fit your wrist.

Ammonites first appeared around 240 million years ago.  They were prolific breeders, lived in schools, and are among the most abundant fossils found today. They went extinct with the dinosaurs 65 million years ago. Scientists use the various shapes and sizes of ammonite shells that appeared and disappeared through the ages to date other fossils.
