Art Deco 18k White Gold Old European Cut Diamond & Sapphire Ring

An exceptional Art Deco statement ring combining icy old-cut diamonds with richly saturated blue sapphires in an elaborate geometric design.

Crafted in 18K white gold and weighing 5.1 grams, the elongated navette-style face is set throughout with natural old-cut diamonds described as D–E color and VVS clarity. Deep blue square-cut sapphires are arranged in striking linear channels, creating the crisp blue-and-white contrast so closely associated with fine Art Deco jewelry.

The design is exceptionally detailed, with delicate milgrain borders, pierced openwork, scrolling elements and engraved shoulders. Viewed from the side and reverse, the craftsmanship is just as impressive, with an airy gallery allowing light to reach the stones.
