Vintage 14k Plum Gold Three-Stone Diamond Bypass Ring
This is a vintage three-stone diamond ring crafted in 14k plum yellow gold. The design features a mid-century modern or late retro-style bypass aesthetic, where two large, polished, wing-like gold sections sweep toward a central vertical row of three round brilliant-cut diamonds. The diamonds appear to be set in white gold or rhodium-plated prongs to enhance their brilliance against the yellow gold shank. The term '14kp' indicates '14k plum,' a hallmark used primarily in the late 1970s and 1980s to certify that the gold content is exactly 14 parts per 24, rather than the slightly lower tolerances allowed previously. The gold surfaces exhibit a high-polish finish with minor surface abrasions and light scratches consistent with regular wear. The diamonds appear to be of industrial to commercial quality, showing visible inclusions under magnification. The structure of the ring is substantial and heavy, with a tapering band that widens significantly at the shoulders to meet the decorative bypass plates. No major repairs are visible, though the prong tips should be inspected for thinning. The piece represents a transition between traditional multi-stone settings and the bold, geometric jewelry trends of the late 20th century.
