Leave it to the Princess of Wales to make a centuries old royal heirloom feel brand new. At the 2025 Wimbledon Championships, Kate Middleton served a subtle style moment that had jewellery sleuths (like us) zooming in just like (Charlotte’s Pandora bracelet). Since Prince William proposed in 2010 with Princess Diana’s legendary 12-carat Ceylon, Kate’s ring finger has been subject of fascination. She added a traditional welsh gold wedding band when they married in 2011, and has occasionally worn a third eternity ring. Wimbledon however, marked the first time all three rings appeared stacked together.
The newest addition? A sapphire and diamond eternity band, thought to be Cartier’s Étincelle, nestled alongside her wedding ring and Diana’s engagement ring. It’s a small change with major significance.
‘Kate’s decision to add a sapphire and diamond eternity band to her ring stack is a masterclass in symbolic storytelling,’ says Nilesh Rakholia, jewellery expert and founder of Abelini. ’It’s not just about adding carats - it’s a personal statement that elegantly merges tradition with her evolving royal identity.’ In other words: with Diana’s ring still front and centre, the sapphire theme running through the stack feels intentional - a branch between generations.
According to Abelini the four ring stack is now estimated to be well into the high six figures (over $400,000). It also taps into the wider trend of ring stacking: a move that lets wearers mix heirlooms with modern pieces to tell their own story. In Kate’s case, the message is clear - she’s honouring the past while making it her own and doing it with quiet confidence.
