Circa 1930 Art Deco sapphire ring framed by fifty rose cut diamonds

Art Deco platinum ring, circa 1930, centred with an octagonal step cut sapphire of deep velvety blue, held within a crisp geometric frame. The plaque head is lined with 50 rose cut diamonds in graduated rows, finished with fine millegrain and a light openwork gallery. Diamond set shoulders taper to a slender band, giving a clean line on the hand. A compact, architectural jewel that still feels quietly modern, in good condition for its age.
