Paris Hilton and Cardi B may be all about their bold engagement rings (check out Hilton鈥檚 20-carat stunner!), but for This Is Us star Mandy Moore, bigger didn鈥檛 equate to better.

As the actress, who debuted her dainty Irene Neuwirth rock on the red carpet this past September, explained to InStyle, she simply is not a huge jewelry gal. 鈥淚鈥檝e never been someone who wears a lot of jewelry,鈥 Moore said. 鈥淚t鈥檚 fun to get dressed up and wear gorgeous pieces for work, but in my real life, I usually just put on a pair of studs.鈥

It was for that reason that the 47 Meters Down star told fianc茅 Taylor Goldsmith that she didn鈥檛 want a huge rock, with the two planning to pick out some simple bands together.

Instead, Goldsmith surprised her with a totally understated gem that was pure Mandy. 鈥淸He] picked out every detail he thought I鈥檇 like, from the round, faceted stone to the rose gold band. It is so me,鈥 she dished. I especially love that the diamond is flat. You can see my skin through it, which makes it even more understated.鈥

The best 2 years. Never not smiling with you, T. 鉂わ笍馃挏馃挌馃挍馃挋

The musician鈥檚 instincts paid off: As Moore, 33, gushed, 鈥淓ven though I thought I didn鈥檛 want an engagement ring, as soon as I saw this one, I couldn鈥檛 imagine the moment without it.鈥
