Millie Bobby Brown has quickly become one of the most beloved celebrities of her generation, captivating fans with her talent, charm, and effortlessly cool style.
Whether the ‘Stranger Things’ star is walking the red carpet or posting a casual selfie, the world is always watching – and obsessing over – what she wears.
In her latest mirror snap, we couldn’t help but notice a special jewel stealing the spotlight: a stunning ring featuring a pink gemstone that’s as rare and radiant as Millie herself.
Fine jewellery and diamond experts at UK retailer Steven Stone have taken a closer look at the ring.

“In Millie’s latest mirror selfie, her accessories are doing just as much talking as her outfit – and the standout is the exquisite ring adorning her right hand. Perfectly complimenting her pink ensemble, the ring features a dazzling oval-cut pink gemstone set within a delicate halo of smaller diamonds, creating a romantic and feminine look.
While it’s difficult to determine the exact carat weight from the photo alone, the centre stone appears to be under two carats. However, what it may lack in size, it more than makes up for in rarity. Judging by its vivid hue and sparkle, the gem is likely to be a natural pink diamond – one of the rarest and most valuable coloured diamonds in the world. Natural pink diamonds are extraordinarily scarce, with the majority historically sourced from the now-closed Argyle Mine in Australia, which produced over 90% of the world’s supply. Since the mine’s closure in 2020, the value of these already-coveted gems has surged.
A high-quality pink diamond of this size could easily be worth $300,000 or more – especially if it boasts strong saturation, clarity, and an expertly cut shape. Thus, if Millie is indeed wearing a pink diamond, she’s not just making a fashion statement – she’s wearing a piece of investment-worthy luxury that’s as rare as it is radiant.”

What about the ring on her left hand?
On Millie’s left hand, she’s wearing her stunning engagement ring from Jake, which showcases a 4-carat round-cut diamond in a classic halo setting atop a simple, elegant band. Designed to maximize brilliance, the round cut is renowned for its timeless appeal and understated glamour.
Symbolising eternity and everlasting love, the diamond’s shape is a fitting choice for Millie, who announced the couple’s engagement with the heartfelt caption: “I’ve loved you three summers now, honey, I want ’em all.”
Adding even more sentimental value, Millie’s ring originally belonged to her mother. Choosing to wear a parent’s engagement ring has become an increasingly meaningful trend, representing a deep connection to family heritage and the enduring nature of love passed down through generations.
At the time of their engagement, our experts estimated the value of Millie’s dazzling ring at approximately $250,000.
