Toi et Moi diamond ring

You and Me engagement ring in 18Kt yellow gold and platinum, (hallmark: owl and mascaron), decorated in its center with two old-style cut diamonds weighing a total of approximately 0.45 Ct (estimated color G, estimated clarity SI), in a surround of rose-cut diamonds. Edwardian work, Circa 1900, Belle Epoque. Gross weight: 3.38g Ring size: 55 (diameter 17.50 / US 7.25). Height: 1.00 cm Condition: very light micro scratches on the gold and platinum parts, and wear on the setting, light abrasion and shocks on the diamonds, see photos. The diamond crystallizes between 150 and 750 km under the Earth's mantle. At this depth, the pressure is more than 50,000 times higher than atmospheric pressure. This compresses the atoms together, which gives the diamond its great hardness and brilliance. All our engagement rings.
