The model sweetly honored her baby boy, Jack Blues, with new jewelry, sporting a diamond “mom” ring. She wore the style on her left hand in a photo posted to her Instagram Story Tuesday, nearly two weeks after she gave birth.

The Isa Grutman Jewelry design features .21 carats of diamonds set in 14-karat gold and retails for $1,980. It was designed by Isabela Grutman, wife of hospitality magnate and A-lister BFF David Grutman, whose jewels have also been spotted on Serena Williams and Victoria Beckham.

In addition to the bauble on her pointer finger, Bieber gave a glimpse of her massive upgraded engagement ring in the upload.

“Ready for fall over here,” the new mom, 27, wrote in reference to her brown manicure.

The former “Drop the Mic” host had a French manicure when her husband, Justin Bieber, debuted their son via Instagram earlier this month. “WELCOME HOME,” the “Baby” singer, 30, captioned the Aug. 23 snap of Jack’s foot.

The Grammy winner played a role in the “more muted nudist white micro French” look, Hailey’s nail artist told Vogue at the time.

“Justin has been choosing Hailey’s nail design lately, and it was his request,” Zola Ganzorigt said.

The couple have yet to share additional details about their newborn — but model Adwoa Aboah did reveal the little one’s birthdate in an Instagram comment.

After Hailey congratulated the 32-year-old for the birth of her own child on Aug. 23, Aboah commented, “a day apart. 💔💔💔🐣🐣🐣.”

Hailey revealed her pregnancy news in May, debuting her baby bump in photos from her and Justin’s Hawaii vow renewal.

The Rhodes creator explained to W magazine in July why she waited six months to bare her belly.

“I didn’t have a belly, really, until [then],” she said last month. “I was able to wear big jackets and stuff. I probably could have hid it until the end.”
