Art Deco Style Platinum Sapphire and Diamond Domed Bombe Ring

£2,385.00

Art Deco style platinum ring, the domed circular plaque set with an oval sapphire within a calibre cut sapphire cross and diamond set scrolls.

The plaque is domed and stands well clear of the finger. An oval sapphire is rub over set at the crown, and four arms of calibre cut sapphire run out from it to make a cross, dividing the dome into quarters. Each quarter is filled with pierced diamond set scrollwork, and the sides carry further calibre cut sapphires so the ring is decorated all the way round rather than only on top.
