Vintage Heart-Shaped Onyx & Diamond Ring — 14K Yellow Gold, Size 2.75

$436.00 $545.00

This vintage 14K yellow gold onyx ring features a glossy heart-shaped black onyx tablet, bezel-set and accented at the center with a tiny natural old mine cut diamond — a rare antique cut that brings soft, candlelit sparkle to the bold black surface. Elegant engraved detailing along the shank adds texture and depth to the piece.

Though unmarked, the ring has been tested and confirmed solid 14K gold. The lack of a hallmark is consistent with its history: a previous owner had the ring professionally resized down to a petite size 2.75, making it a perfect pinky ring today. During resizing, hallmark stamps are often thinned or removed entirely — a typical occurrence in older rings that have been customized over time.
