The Agoura Hills Antique Engagement Ring. A wonderful piece of wearable architecture, our circa 1920s antique 3 stone diamond & sapphire trinity ring is a show stopper. Boasting over 6 carats of dazzling fire, a 3 carat velvety-blue sapphire is embraced by a pair of old European brilliants of just under 3 ctw. Includes Independent Certified Appraisal $36,000, offered at an outstanding value for such a rare jewel.
