Pictured here is a very rare and genuine modernist ring designed and handmade by artisan jewelry designer Susan Cummings. This ring is fully hallmarked and signed. This is a stunning piece, it's a little work of art that is guaranteed to turn heads. This piece is vintage and most likely one of a kind. The ring measures a 5-1/4 on the mandrel. The Black Onyx Ball moves with the ring to make it easier to slide on. The onyx is approx 16mm. This is simply gorgeous. Please see all photos and feel free to ask questions.
