Art Deco Platinum Rose Cut and OEC Diamond Accented Three Stone Semi Mount Ring

Three empty circular settings define this antique platinum semi-mount, with a slightly larger center mount flanked by two matching side mounts. Each raised setting features projecting prongs above a scalloped, diamond-accented gallery, giving the mounting a crown-like profile. Rose cut and old European cut diamonds embellish the galleries and shoulders, while fine milgrain borders articulate the curved edges and narrow shoulder panels. Open arches beneath the settings reveal the layered construction, extending the decorative detail beyond the ring’s face. The shoulders taper into a smooth shank, balancing the elaborate mounting with a restrained band. The center opening measures 7.5 × 7.5mm, and each side opening measures 7 × 7mm; all three primary stones are absent.
