A striking expression of early 20th century design, this elegant sapphire and diamond plaque ring captures the moment where the softness of the Edwardian era gave way to the bold geometry of Art Deco.
Crafted in luminous 18ct white gold, the elongated rectangular face is beautifully balanced and architectural, drawing the eye with its graceful symmetry. At its heart, a constellation of vivid blue sapphires—centred around a slightly larger stone—glows with a rich, velvety tone, their colour intensified by the cool brilliance of surrounding old cut diamonds.
The diamonds, each individually set, offer a gentle, romantic scintillation unique to antique cuts—subtle flashes rather than modern brilliance—enhancing the ring’s refined, almost ethereal presence. Fine milgrain edging and delicate openwork lend texture and intricacy, revealing a level of craftsmanship that rewards close attention.
Slender shoulders and a lightly tapered band ensure the face remains the focal point, allowing the ring to sit elegantly on the hand while still delivering a confident sense of presence. The elongated proportions create a flattering, lengthening effect on the finger—one of the most sought-after silhouettes of the period.
Dating to circa 1920, this is a piece that bridges two iconic design movements, making it as versatile as it is distinctive. Romantic yet structured, delicate yet impactful—it is equally suited as a unique engagement ring or a signature addition to a thoughtfully curated collection.
A beautifully composed antique ring, rich in character and quietly captivating.
