Diamond Plaque Ring

A vintage diamond plaque ring in 18ct yellow gold, centred on a square platinum-topped setting with approximately 0.75ct of old-cut diamonds. Set on the diagonal, the geometric plaque creates a balanced composition with strong period character and a refined architectural profile. The cluster of old-cut diamonds is arranged within intricate millegrain detailing, allowing each stone to contribute to the overall brilliance while preserving the soft, distinctive character of antique diamond cuts. The platinum setting provides contrast against the warm yellow gold shank, with open shoulders adding lightness to the design. Confident in proportion yet easy to wear, this diamond plaque ring is a versatile vintage piece that transitions effortlessly from everyday wear to evening occasions. Its combination of old-cut diamonds, platinum detailing and yellow gold reflects the enduring appeal of early twentieth-century jewellery design.
