What We Know About Millie Bobby Brown and Jake Bongiovi's Upcoming Wedding

Bongiovi proposed to Brown with a round-cut solitaire diamond engagement ring, estimated to be anywhere from 3 to 3.5 carats. The large center stone is highlighted by her simple, thin gold band.

In her interview with The Sunday Times, Brown revealed that the ring actually belonged to her mom, Kelly. "I've always loved that ring. It's always stuck out to me, so she gave it to Jake," Brown said. "They were in cahoots about the whole proposal. I love that I can always keep a piece of my mum with me."
