18K Bicolor Gold Ring with Diamonds — Vintage Designer Style Striking wide band ring in 18K yellow and white gold, featuring a bold architectural design with an open oval cutout at the centre front. The cutout is elegantly framed by a curved diamond-set arc in white gold with yellow gold detailing, set with approximately 8 round brilliant-cut diamonds in pavé/channel setting. The contrast between the warm yellow gold band and the cool white gold setting creates a sophisticated two-tone effect characteristic of high-end Italian goldsmithing of the 1970s–1980s. Metal: 18K yellow and white gold (bicolour) Stone(s): Round brilliant-cut diamonds (approx. 8–10 stones) Setting: Pavé / channel along curved arc Style: Wide band with open oval cutout — vintage designer aesthetic Condition: Very good vintage condition — some light patina consistent with age
