All the Details on Kate Hudson's Two Unique Engagement Rings

Kate Hudson is officially engaged to longtime boyfriend Danny Fujikawa after five years of dating. The How to Lose a Guy in 10 Days star debuted her gorgeous new bling at the Met Galaon Monday, September 13, giving all of us a glimpse at the rock.

The stunningly unique sparkler practically stole the show, and even coordinated with her beautiful Michael Kors ensemble. The rectangular cushion-cut stone has a warm, golden brown hue and is set in a thin rose gold band adorned with more smaller diamonds.

Kathryn Money, SVP of Merchandising and Retailer at Brilliant Earth, told Brides that the diamond is most likely somewhere between six and eight carats and the whole ring would cost around $175,000 to $225,000, depending on the characteristics of the center and side stones.

The Fabletics founder's ring sparkled in the light at the prestigious event, and reflected the hues in her blush-colored two-piece gown and feather opera jacket. Her warm maroon eye makeup complimented the stone of similar color tones.

"We love that her ring showcases an understated timeless silhouette, with warm tones on a delicate band," says Money. "She’s such a fearless spirit, and this uniquely fancy diamond shape gives the perfect amount of personal touch to a timeless style."

Hudson announced the exciting news just hours before attending the Met Gala, which was themed "In America: A Lexicon of Fashion." She posted a shot of her and the musician, with whom she shares a two-year-old daughter, smiling and about to share a kiss on what appears to be a hike, as Hudson rests her hand on his chest.

In the photo, Hudson isn't wearing the unconventional diamond ring she debuted at the Met, but rather a vintage-looking band that appears to include pearls and rubies, leading us to believe the actress actually received two rings from Fujikawa. "Let’s go! 👰‍♀️💒🤵🏻‍♂️," she captioned the post. Shortly after sharing the news, Hudson was all dolled up and ready to attend fashion's biggest night of the year—along with a sparkling new accessory that really elevated her whole look. Congratulations, Kate!
