In 1981, Lady Diana Spencer stepped into the global spotlight with a ring that would redefine engagement jewellery for generations. Nestled within a halo of brilliant diamonds, her deep blue Ceylon sapphire was bold, regal, and utterly unforgettable. While sapphires had always held a place in fine jewellery, Princess Diana’s choice brought coloured gemstone rings—especially sapphire engagement rings—firmly back into the limelight.
What made Diana’s ring so revolutionary? At a time when most engagement rings featured diamonds as the centrepiece, her selection of a vibrant 12-carat oval sapphire was both traditional and radical. The ring, set in 18ct white gold and encircled by 14 solitaire diamonds, was inspired by a design in Garrard’s royal collection—but unlike most royal jewels, it wasn’t custom-made. It was available from the catalogue, which meant, in theory, anyone could buy it. And many did.
Sapphires were suddenly seen not just as beautiful, but as romantic, powerful, and personal. The ring’s popularity soared again when Prince William gave it to Kate Middleton upon their engagement in 2010, cementing its legacy as the most famous engagement ring in modern history.
For collectors and vintage lovers, Diana’s ring reignited interest in antique and vintage sapphire rings. From Georgian sapphire clusters to Victorian cushion-cut solitaires, these timeless pieces echo the enduring appeal of sapphires as a symbol of wisdom, loyalty, and nobility.
Whether you're drawn to sapphire’s royal connections or simply love its rich hue, the stone remains a meaningful and striking choice—proof that a single ring really can change everything.
