Millie Bobby Brown's Engagement Ring: A Cushion Cut Heirloom

Having steered the ship of Queensmith's creative content since 2017, India finds immense satisfaction in arming clients with the information they're seeking, identifying and analysing trends, and exploring buying habits.

Millie Bobby Brown and Jake Bongiovi’s engagement made headlines in April 2023 – not just for the romantic proposal, but for the stunning ring that followed. Here’s everything we know about Millie’s engagement ring, from its carat weight and design to its sentimental backstory and how you can recreate the look.
How did Jake Bongiovi propose to Millie Bobby Brown?
Millie Bobby Brown and Jake Bongiovi share a passion for scuba diving, so it’s no surprise that Jake chose an underwater setting for his proposal. During a dive, he presented Millie with a shell containing a ring. However, the ring slipped off her finger and began to sink. Jake heroically retrieved it, despite warnings about the dangers of deep dives. Upon resurfacing, he presented Millie with a family heirloom ring from her mother, making the moment even more meaningful.
What style is Millie Bobby Brown's engagement ring?
Millie’s engagement ring features a cushion cut diamond estimated to be between 3–4ct, set in a cushion shaped halo on a scallop diamond band. The ring is either white gold or platinum, adding to its timeless elegance.
How much is Millie Bobby Brown's engagement ring worth?
If the diamond is lab grown, the ring could be worth £10,000 ($13,500 USD) – or if natural, as high as £100,000 ($135,000 USD). Since it's an heirloom ring, the diamonds are likely natural – as lab diamond engagement rings are relatively new to the market. Queensmith's expert gemmologists identify the diamond as being fairly low on the colour scale, likely below H and almost appearing fancy yellow. This would reduce the value of the diamond by forty to fifty per cent.
Is Millie Bobby Brown married?
Millie Bobby Brown is married – she tied the knot with Jake Bongiovi, son of musician Jon Bon Jovi, in a private ceremony in May 2024. The wedding was described as intimate and lowkey, with only their closest family and friends in attendance. The couple then hosted a second destination wedding in Tuscany later that year, with Millie's Stranger Things co-star Matthew Modine officiating the ceremony.
