Provenance
Original to c.1925, this incredible Art Deco flanked solitaire is the definition of sophistication. Set to centre with a natural cushion-cut sapphire with an moody midnight blue-hue which dances in the light beautifully. Claw-set in an open-back setting and flanked by diamond-set shoulders.
On either side, three baguette-cut diamonds graduated in size and rub-over set, bordered by polished edges. The gallery is a miniature masterpiece, with tiered linear open-work delicately crafted in platinum. Beneath the central sapphire is a refined criss-cross lattice design. The gallery feels sleek and architectural in style - perfectly encapsulating the Art Deco aesthetic. The shoulders are open and feature linear open-work, seamlessly flowing to a solid platinum band.
