Details on Millie Bobby Brown’s ‘classic’ engagement ring from Jake Bongiovi

Just call it “Stranger Rings.”

Millie Bobby Brown announced on Tuesday that she’s engaged to Jake Bongiovi, showing off her diamond ring in a black-and-white beach photo.

The 19-year-old “Stranger Things” actress captioned her pic with a Taylor Swift lyric: “I’ve loved you three summers now, honey, I want ’em all.”

While close-up images of the ring haven’t been released yet, multiple diamond experts tell Page Six Style the sparkler appears to feature either a round- or cushion-cut center stone.

“Round [diamonds] are timeless, super classic and will never go out of style,” says Olivia Landau, GIA-certified gemologist and founder of The Clear Cut, estimating the rock at between 3 and 3.5 carats.
