Hailey Bieber Shows Off Birthstone Ring for ‘Jack’ and ‘Mama

Hailey Bieber

is keeping son Jack Blues close to her heart, sartorially speaking.

Bieber, 28, debuted a massive two-stone ring via her Instagram Story on Saturday, December 21, where a square-shaped peridot diamond sat beside a teardrop bauble in topaz on a gold hand.

She explained that the peridot square represented “Jack,” while the topaz was for “Mama.”

Hailey gave birth to her and husband Justin Bieber’s firstborn son in August, which makes peridot the baby’s birthstone. Hailey, for her part, was born in November, which is marked by topaz and citrine stones.

Hailey, who turned 28 in November, has upgraded her jewelry collection since becoming a mom. She often wears necklaces that read “JBB” or “Mama” to denote Jack’s initials or her new role, respectively.

In addition to raising baby Jack, Hailey recently returned to work as a model and the founder of Rhode Skincare.

“I’m only doing what feels comfortable for me physically, mentally and emotionally,” she told Women’s Wear Daily in October. “Mistakes are going to happen … [there] “will be bumps in the road, which are out of your control. But you need to pivot, run and work with them as they come.”

Shortly after Hailey gave birth, a source told Us Weekly that she and Justin, 30, were in “total bliss” with the newborn.

“Hailey is enjoying and savoring these moments being a new mom,” the source exclusively told Us in August. “She is over the moon and in mom zone, and completely focused on the health of the baby.”

Hailey’s father, Stephen Baldwin, later revealed in December that Jack has already started to grow “like a weed.”

“Actually, he looks like a little plump potato,” Baldwin, 58, told TooFab on Monday, December 16. “He’s so cute. I can’t stand it. I want to say so much.”
