Vintage Platinum Diamond Semi Mount Engagement Ring

An elevated, open center setting anchors this antique platinum engagement ring mounting, flanked by single cut diamonds totaling 0.08ctw. The shoulder diamonds sit between defined metal bars, with stepped accents and curved engraved details transitioning into a tapered knife edge shank. Rectangular openings beneath the center and shoulders give the gallery an architectural profile, characteristic of Art Deco’s emphasis on geometry and symmetry. The bright platinum surfaces unify the diamond accents while keeping the composition restrained. The center stone is absent, and the mounting opening measures 7 × 7mm.
