A striking original Art Deco blue zircon and diamond ring, crafted entirely in solid 18ct white gold and dating to the 1920s–1930s. At its centre sits a beautifully coloured natural blue zircon in a crisp rectangular step cut, measuring approximately 8.25 × 6.25 × 5mm and estimated to weigh 3ct. The stone displays a vivid, saturated blue colour with exceptional brilliance and the lively flashes of fire for which natural zircon is so highly prized.
The zircon is securely held by four substantial corner claws and flanked by elegant stepped geometric shoulders set with sparkling natural diamonds. The clean architectural lines, balanced proportions and strong symmetry are hallmarks of original Art Deco design, while the all-white 18ct gold setting enhances both the brilliance of the diamonds and the vivid blue of the centre stone.
With its bold rectangular centre stone and refined diamond-set shoulders, this is a timeless and highly wearable Art Deco ring, equally suited as a distinctive engagement ring or an exceptional addition to any antique jewellery collection.
