Antique Sapphire Ring of Platinum Topped 15k Gold

An elegant antique ring circa 1920, centering a finely proportioned oval flame-fusion synthetic sapphire in a delicate millegrain setting. The sapphire is framed by a dome of old European-cut diamonds, creating a striking contrast between the rich blue center stone and the soft, romantic sparkle of the surrounding diamonds. The platinum-topped gold mounting lends additional refinement to the beautifully sculpted design.

The ring measures approximately 0.70 inches north to south across the face and weighs 3.43 grams. It remains in great antique condition, with all stones secure and the intricate details of the setting well preserved.

Currently a size 3.5, the ring may be resized within reason for an additional charge.

The sapphire has been identified through Raman spectroscopy, a non-destructive analytical technique that provides precise gemstone characterization. Metal content has been verified using XRF (X-ray fluorescence) analysis in conjunction with traditional jeweler’s acid testing, confirming a platinum-topped 15 karat gold mounting.
