Hailey Bieber Honors Baby Jack With Toi et Moi Ring Featuring Their Birthstones

Hailey Bieber turned to her Instagram Stories on Saturday to show off another heartfelt tribute to her four-month-old son, Jack Blues Bieber — a special "toi et moi" ring featuring their two birthstones.

The proud mom added helpful labels to the gems seen nestled in the photo: On the "Jack" side of the ring is an emerald-cut peridot, the birthstone for August. On the "Mama" side is a slightly angled pear-shaped citrine, one of the official birthstones for November.

Traditionally, the “toi et moi” ring symbolizes two souls becoming one and is predominantly used for bridal jewelry. (The French phrase “toi et moi” means “you and me” in English.)

The concept is attributed to Napoleon Bonaparte, who, in 1796, was a 26-year-old officer and still eight years removed from the French throne when he presented a “toi et moi” ring to his beloved Josephine on the occasion of their marriage. Josephine's bypass-style ring featured two pear-shaped gemstones, one diamond and one sapphire, set in opposite directions.

Over time, the emperor's concept has been reinvented in a number of ways. For instance, in one variation, the stones aren't the same shape and in another they're not oriented in opposite directions. In Bieber's interpretation, it represents her special bond with baby Jack.

This is not the first time Bieber has embraced mom-themed jewelry.

In an early September post on Instagram, Bieber revealed to her 54 million followers a dimensional, diamond-embellished “MOM” ring on the index finger of her left hand.

On the ring finger of the same hand was her upgraded 18-carat oval-cut diamond engagement ring that she received in late spring. The ring commemorated the renewal of her and Justin Bieber’s wedding vows after five years of marriage, as well as the exciting news that they were expecting their first child.

Her previous engagement ring — with an oval-cut diamond said to weigh between 6 and 10 carats — can be seen on the pinky of her right hand.

Then, in October, the model and cosmetics entrepreneur was photographed wearing a necklace that featured the bubble letters "JBB"— Jack's initials — as well as a gold bracelet with Jack's name spelled out in black text.
