Art Deco 1.05 Carat Old Cut Diamond Trilogy Ring, circa 1930

An exciting and fantastically different ring. The central an old mine cut diamond – and the pair of old European cuts either side of it – are set in octagonal rubover platinum collets, which are suspended within an 18k white gold outline.
