Lady Eliza Spencer – Princess Diana’s niece – has announced her engagement to long-time partner Channing Millerd, after nearly a decade together.
Eliza, the daughter of Charles Spencer and former model Victoria Aitken, shared the joyful news on Instagram on Thursday. Her tech executive fiancé proposed during a romantic sunset dinner in Santorini, Greece, surrounded by flowers and candlelight.
She posted a series of stunning photos capturing the moment, including a close-up of her breathtaking pear-shaped diamond engagement ring. In true Spencer style, Eliza’s ring is nothing short of dazzling – and much like her late aunt Diana’s iconic sparkler, it’s making waves.
Diamond experts at UK jeweller Steven Stone has already weighed in with expert insights into the eye-catching piece.


“Lady Eliza Spencer bears a striking resemblance to her late Aunt, Princess Diana – and it seems her taste in fine jewellery is just as exquisite. The daughter of Charles Spencer recently became engaged, receiving a breathtaking ring that beautifully blends modern glamour with timeless elegance.
At its centre is a dazzling 2.50 carat pear-cut diamond, symbolising elegance, individuality, and a love that endures. The stone is encircled by a delicate halo setting – a subtle nod to the iconic engagement ring worn by Princess Diana, which famously featured a deep blue oval-cut sapphire surrounded by diamonds.
Eliza’s ring is likely set on a sleek platinum band, chosen for its durability and classic finish – a fitting tribute to a new chapter rooted in love, legacy, and enduring style.
I’d estimate the sparkler to be worth around $50,000, putting it on the more modest end of the spectrum for royal engagement rings – especially when compared to Princess Diana’s iconic ring, now worn by Kate Middleton, which is valued at £390,000.”
