Some gemstones achieve a level of recognition that transcends fashion or era. One of the most famous examples is the striking oval Ceylon sapphire surrounded by diamonds that has become one of the most recognisable engagement rings in the world.
While the story behind the ring is widely known, the true fascination lies in the gemstone itself — a remarkable 12-carat sapphire whose colour, scale, and craftsmanship exemplify the enduring allure of fine coloured stones.
The Centrepiece: A 12-Carat Ceylon Sapphire
At the heart of the ring is a deep blue Ceylon sapphire, cut in an oval shape that maximises both colour and brilliance. Sapphires from Sri Lanka — historically known as Ceylon — are highly prized for their vivid, luminous blue tone.
What distinguishes these sapphires is their balance: neither too dark nor too pale, but displaying a vibrant royal blue that appears almost velvety under light.
Large natural sapphires of this quality are rare. At 12 carats, the stone commands exceptional presence while maintaining elegant proportions on the hand.
The Halo: Diamonds Enhancing Colour
Surrounding the sapphire is a halo of 14 brilliant-cut diamonds. Rather than competing with the centre stone, the diamonds serve a specific purpose: enhancing the sapphire’s colour.
White diamonds reflect light back into the gemstone, intensifying its depth and creating a striking contrast. This halo design is now widely emulated in engagement rings because it frames coloured stones beautifully while adding extra brilliance.
A Design That Became Iconic
The ring’s setting — 18-carat white gold with a diamond halo — strikes a perfect balance between statement and refinement.
The oval sapphire shape elongates the finger, while the halo adds structure and sparkle. It is a design that feels both classic and contemporary, which explains why it continues to influence engagement ring styles decades after it was first created.
Today, sapphire halo rings remain among the most requested coloured gemstone designs in bespoke jewellery.
The Care of Precious Gemstones
Sapphires are among the hardest gemstones, second only to diamonds, making them suitable for everyday wear. However, larger gemstones — especially heirloom pieces — require careful maintenance.
Regular inspections help ensure that:
prongs remain secure
stones stay properly aligned
the metal setting maintains its integrity
Professional cleaning also restores brilliance to both sapphire and diamonds, allowing the ring to retain its original glow.
Why Sapphires Continue to Captivate
Beyond their beauty, sapphires carry deep symbolism. Traditionally associated with wisdom, loyalty, and protection, they have long been favoured for engagement jewellery.
Their durability, rich colour, and rarity make them one of the most compelling alternatives to traditional diamond centre stones.
At SICO, we believe gemstones should be chosen not only for their brilliance, but for their story and character. Few stones embody that philosophy as completely as a fine sapphire.
