This Glee Star Just Debuted the Classic — and Very Large — Engagement Ring of Our Dreams

When we first saw Dianna Agron sitting front row at Erdem's Fall '16 show, we were all, "Gorgeous dress choice, girl!" But then, we caught a glimpse at the star's left hand and — gulp! — there it was: the classic, yellow-gold engagement ring of our dreams.

The star quietly got engaged to Mumford & Sons' Winston Marshall over the holidays, and really, what better time to show off that large round diamond than at London Fashion Week? The simple yet statement-making design went perfectly with her floral dress, and it's a design that'll never go out of style — so hopefully she'll continue to wear it with all of her red carpet looks.

Read on to see Dianna's new piece of jewelry in all its glory, then shop a similar something for yourself if you're so inclined. Congrats to the bride-to-be!
