When Prince William proposed to Kate Middleton in 2010 with Princess Diana’s iconic sapphire and diamond ring, the world fell in love all over again. The now-Duchess of Cambridge brought sapphire engagement rings back into the spotlight, and more than a decade later, their popularity is stronger than ever.
At Ellisons Jewellers in Belfast, we’ve seen how this timeless style continues to inspire proposals across Northern Ireland and Ireland. Whether you’re royal-obsessed or simply love the deep, rich beauty of sapphires, this guide will help you explore the magic behind Kate’s ring and find a style that suits your own love story.
What Makes Kate Middleton’s Engagement Ring So Special?
Kate’s engagement ring is nothing short of iconic. Originally worn by Princess Diana, the 12-carat oval Ceylon sapphire is surrounded by 14 solitaire diamonds and set in 18ct white gold. Its bold colour, classic halo design, and royal legacy make it one of the most famous rings in the world.
This elegant combination of sapphire and diamond has become a favourite among couples who want something traditional with a twist – a ring that combines timeless beauty with a sense of individuality.
Why Choose a Sapphire Engagement Ring?
Sapphires are not only stunning – they’re also full of meaning. Traditionally associated with loyalty, truth, and wisdom, sapphires are perfect for symbolising a lifelong commitment. They’re also incredibly durable, ranking just behind diamonds on the Mohs hardness scale, making them ideal for everyday wear.
At Ellisons, our diamond rings collection includes a curated range of sapphire engagement rings that echo the elegance of Kate Middleton’s style while offering unique design twists of their own.
