1970s 18k yellow gold sapphire and diamond ring — a bold, sculptural cocktail ring with a richly saturated faceted sapphire set at the center and six brilliant diamonds arrayed across the domed shoulders. The deep blue sapphire is faceted to catch light from every angle and is embraced by a high-polished, rounded gold dome that gives the piece a strong, architectural silhouette typical of late-20th century design.
