On Saturday, Michelle Oh, the London-based based jeweler who designed the star's gorgeous diamond ring, posted a carousel of photos on Instagram revealing the "sentimental" details behind the star's engagement band.
"Bonnie told me that she wanted to create the most special ring possible. Something that was kind of vintage inspired in aesthetic and really one of a kind, like a rare flower in bloom 💐," Oh wrote of Feldstein's fiancé.
She continued, "The back and the inside of the ring is just as beautiful as the outside, and we were also able to incorporate a very sentimental little diamond to the inside of the ring which used to feature on Bonnie's mum's ring ♥️ it's details like these that make a ring extra special."
The Impeachment: American Crime Story actress, 29, shared her love for the ring in the post's comment section, writing, "the most beautiful ring to ever exist i'm so grateful." Roberts also commented, "Beyond my dreams and imagination! Most perfect ring for the most perfect girl @beaniefeldstein ❤️❤️."
