Art Deco 18ct Gold & Platinum, Opal and Diamond RingThis is a very fine Art Deco ring, which focuses on a richly coloured opal.

Six diamonds are set in stepped form on each shoulder. The ring sits flat on the finger and is both grand and wearable a perfect and unique engagement ring, or something sparkling
