Hailey Bieber Is Rockin' an Upgraded 18-Carat Diamond Engagement Ring

Model and skincare entrepreneur Hailey Bieber is rockin' a new diamond engagement ring from her pop star husband, Justin. The couple has had a lot to celebrate recently, and the amped-up 18-carat ring commemorates both the renewal of their wedding vows after five years of marriage and the announcement that they are expecting their first child later this year.

Under the caption, "little cherry blossoms on my nails little cherry blossom in my belly," Hailey Bieber, 27, shared a 10-slide carousel on Instagram, which offered a glimpse of the new ring — subtlety and barely in frame — on the final slide.

The photo shows her sipping a beverage while the new dazzler nestles against her diamond wedding band on the ring finger of her left hand.

Interestingly, her previous diamond engagement ring — said to weigh between 6 and 10 carats — has found a new home on the pinky of her right hand.

Jewelry-industry pundits placed the value of the original engagement ring at $500,000 and the upgraded version in the range of $1 million to $1.5 million. Both diamonds are ovals set in yellow gold.

Vogue.com reported that the new ring was designed by celebrity jeweler Lorraine Schwartz. The original ring was designed by Solow & Co.

Hailey and Justin Bieber, 30, commemorated their five-year anniversary by renewing their vows in Hawaii on May 9. Hailey's due date has not been formally announced, but fans believe the baby will arrive this fall.
