The fossil is from Utah and is about 30 million years old! It is attached with a Sterling Silver hand-made prong setting to a soldered chain and an all Sterling Silver key ring. The trilobite, the famed indicator fossil of the Cambrium, is unusually large for that locality. He-or she-has no defects and is a complete, natural fossil.
Dimensions: ring 1” diameter, fossil 30mm by 19mm.
