Vintage 14K Two-Tone Gold .25ctw Diamond Bypass Ring – Circa Late-1960s - 70s 

A refined ring with elegant two-tone styling, sculptural crossover lines, and timeless mid-century modern appeal.

This elegant, vintage 14K two-tone gold diamond ring from Fine Jewelers Guild, showcases a graceful bypass design accented with natural round brilliant cut diamonds in a refined mid-century modern setting. Dating to approximately the late 1960s through 1970s, this ring features sculptural flowing lines and subtle contrasting surface finishes characteristic of fine jewelry from the era. 

The ring is set with seven natural round brilliant cut diamonds measuring approximately 1.8–2.1mm each, with most stones measuring 2.0mm in diameter. The diamonds are bead set within a polished white gold ribbon motif that sweeps gracefully across the finger in a timeless crossover design.

The yellow gold body of the ring features softly contrasting polished and satin-finished surfaces beneath the white gold diamond setting, creating dimensional depth and visual contrast that enhances the sculptural quality of the design. The combination of warm yellow gold, cool white gold, and bright natural diamonds gives the ring an understated yet sophisticated vintage aesthetic. 

The low-profile mounting and elegant proportions make this ring exceptionally wearable for everyday use while retaining the distinctive character of authentic vintage fine jewelry. #90 #A.
