The Princess Kate LD Sapphire and diamond engagement ring. July Antique of the Month
Antique of the Month: The Sapphire & Diamond Cluster Ring Inspired by Royalty
This month’s featured piece from the Lannah Dunn antique collection is a breathtaking 18ct gold and platinum oval sapphire and diamond cluster ring, crafted in France circa 1930. A rare and authentic treasure, this heirloom is strikingly reminiscent of one of the most famous engagement rings in the world — that of Catherine, Princess of Wales.
Often referred to as the Princess Kate ring, the now-iconic design was originally chosen by Lady Diana Spencer in 1981 upon her engagement to Prince Charles. Designed by Garrard & Co., the British Crown Jeweller, Diana’s ring featured a 12-carat oval Ceylon sapphire surrounded by fourteen solitaire diamonds in a white gold setting — a style that quickly became one of the most replicated and admired designs in the world of fine jewellery.
Our antique cluster ring embodies the same royal elegance, with its timeless oval silhouette and shimmering diamond halo. It features a richly coloured oval sapphire, estimated at over 3.0 carats, likely of Australian origin, prized for its deep blue brilliance and exceptional clarity. The sapphire is surrounded by a halo of old-cut diamonds, each hand-faceted in the early 20th century to sparkle optimally in the soft glow of candlelight — a signature of the Art Deco, and earlier periods.
Unlike modern, mass-produced rings, this piece is handmade, from the gem-cutting to the setting and frame, showcasing the extraordinary craftsmanship and refined aesthetic of 1930s French jewellers. The platinum setting secures each gem with precision and elegance, while the 18ct yellow gold band adds warmth and a subtle contrast that enhances the overall richness of the design.
Whether you’re a collector of royal-inspired jewels, a lover of Art Deco design, or searching for a one-of-a-kind engagement ring with provenance and prestige, this antique sapphire and diamond ring is a piece of wearable history.
Exclusively available at Lannah Dunn Fine Jewellery, this ring is a rare opportunity to own a regal jewel of enduring beauty — one that tells a story nearly a century old, yet still captivates hearts today.
Sapphire and diamond engagement rings have long been treasured for their timeless elegance and symbolic meaning. The deep blue sapphire represents loyalty and wisdom, while the surrounding diamonds add brilliance and enduring strength—qualities perfect for a lifelong commitment. This oval cluster style, made famous by Princess Diana and now beloved by Princess Kate, continues to captivate brides around the world. Whether you’re searching for a vintage engagement ring with history, a royal-inspired sapphire ring, or a one-of-a-kind antique cluster ring, this exquisite 1930s French design offers unmatched beauty and rarity. Ideal for those seeking a sustainable and storied alternative to modern rings, this piece is an heirloom in waiting.
