Early Victorian 15k Turquoise Diamond Ring

A lovely c. 1830-50s early Victorian ring, set with an old cushion cut diamond in a halo of Persian turquoise cabochons. The setting and shank test as solid 15k gold. The striated shank curves and flares seamlessly into a trifurcated shoulder. The shape of the ring face is reminiscent of forget-me-not flowers, suggesting this ring may have been made to be given as a sentimental or romantic gift. Common for the early Victorian era, the setting style of the stones are cut-down collets, and the shank interior is unmarked (hallmarking was required for mourning rings, but would not be adopted en-masse for dress rings until after 1840).
