Open work Silver design with an oval with a fiery jelly opal glass stone. The surface is a smooth glass cabochon, any detected texture / color variations are below the surface. The back of the stone has age appropriate surface scratching. We have recently dropped the piece causing a small slice of the stone to flake off on the end of the oval. Photo added. Price has been reduced for the imperfection.
1.2 inches. Marked Sterling. Ca., 1900.
