It’s a battle of the (engagement) bands.

Lauren Sánchez and Georgina Rodríguez both flaunted their massive multimillion-dollar rings at Balenciaga’s fashion show on Saturday night.

Photos showed the ladies sitting next to each other in the front row, each dressed in all-black ensembles, making their jewelry the center of conversation at the Paris Fashion Week event.

Sánchez, 55, sported her massive oval-cut diamond on her left hand for the show, while Rodríguez was dripping in diamonds with two rings on her right and left hands.

The ladies’ set of rings is reportedly estimated to be worth approximately $12 million.

The new Mrs. Bezos debuted her giant diamond in June during her lavish wedding week in Venice, Italy.

Designed by celebrity-loved jeweler Lorraine Schwartz, Rare Carat CEO Ajay Anand previously estimated the new bauble could be up to 45 carats in size.

“And knowing Bezos, it’s likely a D flawless, which would put the value easily north of $6 million [for a stone that big],” he told Page Six Style.

Another diamond expert weighed in on the rock, saying it’s “among the rarest and most coveted colored diamonds in the world” and “exceptionally scarce.”

The precious diamond served as an upgrade from Bezos’ original $2.5 million pink diamond engagement ring, which was made up of 20 carats.

Rodríguez, 31, was given her ring by her longtime boyfriend, Cristiano Ronaldo. The soccer star, 40, officially asked for the model’s hand in marriage with the oval cut diamond stunner in August after eight years of dating.

Experts previously told Page Six that the Rodríguez’s sparkler could be worth anywhere between $2 and $5 million.

At the time, Anand estimated the center stone to be of D color and flawless clarity, potentially weighing over 30 carats.
