The Opus Signet Ring centers a round green chalcedony stone on a sunburst-engraved enamel face, framed by a polished sterling silver border. Fine rays radiate out from the bezel-set stone, shifting in tone as the hand moves. Each chalcedony is natural, so its exact green varies slightly from ring to ring, a stone often tied to calm and balance. Tapered shoulders flow into the round face for a classic signet shape. Solid sterling silver gives it weight and a bright finish. A silver signet that anchors a look or layers with plainer bands.
