On what appears to be her right ring finger, Sánchez has been wearing the pink, 30-carat diamond that Bezos proposed to her with in 2023.

Ajay Anand, the CEO and founder of diamond retailer Rare Carat, told Business Insider that its value is likely somewhere in the $3-4 million range.

On her left ring finger, though, Sánchez is now wearing an even bigger rock — this one crystal clear and shaped like an oval.

"Based on visual proportions, we'd estimate it to be at least 45 carats, possibly more," Anand told BI. "And knowing Bezos, it's likely a D Flawless, which would put the value easily north of $6 million."

Sánchez has been wearing the latter piece of jewelry since March. Her Venice wedding marks the first time she's worn it at the same time as her engagement ring.

She paired both pieces with a brown bracelet featuring two letter charms, LB, which could stand for her new name, Lauren Bezos.

Her outfit included a knee-length skirt, a button-down top with puffed short sleeves, and a black handbag.

Sánchez accessorized the classic, conservative look with $505 Tom Ford sunglasses and a white bandana tied around her head.

She stepped into a water taxi while wearing a strapless design from the designer brand's spring 2025 couture collection.

Its tight, metallic corset sat beneath a satin band with embroidered flowers across the chest, and its form-fitted skirt had a matching print.

To complement the dress, Sánchez wore her engagement ring, large stud earrings, and her second massive diamond ring.

Leaving the hotel via water taxi with Bezos, Sánchez wore a 2003 Alexander McQueen dress sourced from Tab Vintage.

Alexis Novak, the founder of Tab Vintage, told BI that the one-shoulder dress, which was handmade and most likely a sample, was designed with stripes of mother-of-pearl buttons.

When Sánchez and Bezos floated into the Aman hotel on Wednesday, she turned bridal style on its head by arriving in all black.

She paired her dress with $510 sunglasses from Celine. The look was simple and chic, and by not wearing white, Sánchez set the tone for her atypical bridal style.
