Hailey Bieber shows off 'mom' diamond ring after welcoming baby boy Jack Blues

Hailey Bieber is embracing her new role as a mother.

The model paid tribute to her baby boy, Jack Blues, by donning a new piece of jewelry — a diamond “mom” ring. She showcased the ring on her left hand in an Instagram Story on Tuesday, just shy of two weeks after giving birth.

The ring, designed by Isa Grutman Jewelry, boasts .21 carats of diamonds set in 14-karat gold and is priced at $1,980. The designer, Isabela Grutman, is the wife of hospitality mogul David Grutman, and her jewelry has been seen on stars like Serena Williams and Victoria Beckham.

In the same post, Bieber also gave a peek at her newly upgraded engagement ring, worn alongside the “mom” ring on her finger.

"Ready for fall over here," the 27-year-old new mom captioned the photo, referring to her seasonal brown manicure.

When Hailey’s husband, Justin Bieber, introduced their son Jack on Instagram earlier this month, Hailey had been sporting a French manicure. “WELCOME HOME,” the "Baby" singer, 30, captioned the Aug. 23 photo of Jack’s tiny foot.

Hailey’s nail artist, Zola Ganzorigt, revealed to Vogue that Justin had a hand in choosing her nail design at the time. 

“Justin has been choosing Hailey’s nail design lately, and it was his request,” Ganzorigt said of the “muted nudist white micro French” look.

While the couple has kept details about their newborn son private, model Adwoa Aboah shared a hint about Jack’s birthdate in an Instagram comment.

After Hailey congratulated Aboah on the birth of her child on Aug. 23, Aboah responded, "a day apart. 💔💔💔🐣🐣🐣," hinting that Jack was born on Aug. 22.

Hailey first announced her pregnancy in May, debuting her baby bump in photos from her and Justin’s vow renewal ceremony in Hawaii.

In a July interview with W magazine, the founder of Rhodes explained why she chose to keep her pregnancy private for six months before revealing her growing belly.
