Antique art nouveau large floral circle round pendant Poinsettia Art deco silver and sterling silver chain atlas.

This sterling silver chain is approximately 19 inches long the chain is signed atlas sterling dependent it’s self I believe is silver over copper and I am not sure if they were original to each other or not the previous owner said they are but that could be an accurate. Very beautiful statement piece!
