To find out more about the gemstones in this ring:
Provenance
Original to c.1920, this incredible cocktail ring was made in San Francisco and features an impressive citrine weighing over 20ct! The citrine has a stunning tangerine orange hue and remarkable clarity. Emerald-cut and claw-set in an open-back setting.
Flanked by diamonds which form the shoulders of the ring, a baguette cut on either side in a rub-over setting, set immediately above and below with a round transitional-cut diamond, grain-set and bordered by millegrain edging. Further set with a round brilliant-cut diamond in a triangular motif.
The gallery features linear open-work with a particular architectural finesse to it, reflecting the contemporaneous dawn of the skyscraper, which is equally fitting for its San Franciscan heritage!
