9ct Gold Aquamarine and Diamond Trilogy Ring, Platinum setting, Size K.5, 1.69g

A vintage three-stone (trilogy) ring in 9 carat gold, set with a central aquamarine flanked by two accent diamonds. The stones sit in illusion-style platinum settings on a gently twisted crossover gold shank, a design typical of the 1930s–1950s.

Hallmarked inside the band "9CT & PLAT", confirming a 9 carat gold shank with platinum used for the stone settings (a common combination of the period, pairing an affordable gold band with the extra strength and bright white finish platinum gives around diamonds).
