Art Deco Era high quality Sterling Large Onyx Marcasite Ring 5.5

This is a unique size, quality and cut ring in sterling and onyx with accent marcasites. It hugs the finger and presents a large surface of intricately framed onyx. A true Art Deco period high quality object. It is marked "sterling" and I left it as is with patina but will polish upon request. In excellent condition, no scratches on the stone.
