An Edwardian Diamond cluster ringA beautiful Edwardian era plaque style diamond cluster ring, featuring a refined rectangular head measuring approximately 12 8 mm and crafted in platinum. The ring is set with two principal old cut diamonds, each approx. 2. 5mm in diameter and estimated at 0. 06ct, flanked by delicate 1. 2mm rose cut diamonds to each side. Classic platinum shoulders transition into a solid 9ct yellow gold band (both tested; no hallmark required for this period).
