Vintage 10KP plumb gold ring featuring an elegant asymmetrical bypass design, the upper section formed as a sweeping fan or crescent accented with a graduated row of small deep red stones and a larger untested diamond, intersected by a graceful curved gold element terminating in an additional untested diamond. The sculptural composition gives the ring an attractive mid-century to late-20th-century cocktail-jewelry appearance, with warm yellow gold providing strong contrast to the red and colorless accents. The interior of the shank is clearly marked “10KP,” indicating plumb 10-karat gold, and the ring measures approximately size 3. The stones have not been removed or laboratory tested; the colorless stones are cataloged as diamonds based on appearance only and remain untested. Condition is good overall with light surface scratching and normal wear consistent with age and use.
