There is something so effortlessly romantic about an antique sapphire and diamond cluster ring — and this one is truly special.
Crafted in rich 18ct yellow gold with a platinum setting, this beautiful piece dates to around 1920, right at the transition between the elegant Edwardian era and the emerging Art Deco period. It carries that perfect balance of delicacy and quiet strength.
At the centre sits a dreamy cornflower blue-violet sapphire, framed by a halo of eight sparkling natural diamonds. The diamonds are bead-set into platinum, allowing them to catch the light beautifully and give off a sparkling white shimmer that contrasts perfectly with the baby blue sapphire.
The shoulders feature platinum kite-shaped geometric details that draw the eye toward the gemstone cluster, while the squared-off yellow gold band gives the ring a lovely sense of structure and presence despite its dainty proportions.
Refined, feminine, and wonderfully wearable, this is the kind of ring that feels both sweet and significant. It would make a truly timeless engagement ring — an original antique with nearly a century of history and a lifetime still ahead.
