Beyoncé Wears Custom Diamond Tiffany & Co. Earpieces (4.5 Carats Worth!) for Her Sold-Out Renaissance World Tour

The chart-topping artist and Tiffany & Co. ambassador has a show-stopping roster of high-fashion stage looks, but perhaps the most exclusive: the sparkling earpieces made for her by the jeweler

There was no doubt Beyoncé's The Renaissance World Tour was going to be a knockout in the style department — and it should also be no surprise that the superstar leveled up on our already-high expectations.

On Wednesday night, the 32-time Grammy winner kicked off her circuit of sold-out shows in Stockholm, Sweden.

Just on her first stop alone (which also marked the musician's first solo concert in seven years) Beyoncé, 41, delivered a 36-track setlist on a stage built for a superstar while wearing a wardrobe of avant-garde designer looks, including a buzzy Mugler bee costume (apt for the queen of the Beyhive), iridescent David Koma ensembles and several Loewe outfits, paired with boots by Stuart Weitzman and Giuseppe Zanotti.

But what even eagle-eyed style savants might have missed throughout the Renaissance fashion extravaganza was the musician's blinged-out Tiffany & Co. in-ear monitors, which performers wear to make sure they can hear their band and sound mixes safely in a loud stadium. Hers are made just for her in platinum with 4.5 carats worth of diamonds!

A tour photo diary shared on Beyoncé's website gives a closer glance at the sparkling in-ear accessory.

In one behind-the-scenes photo, the "Cuff It" singer smiles while showing off the sparkly, and slightly holographic, earbud matching her delicate "ear party" jewelry and chrome winged eyeliner.

The second shows a full look at the pair nestled in a black case alongside that signature Tiffany & Co. blue pouch.

The singer's partnership with Tiffany & Co. goes back more than a year; last April, the former Destiny's Child member became the first person to ever wear Tiffany & Co.'s most expensive diamond necklace: "The Historic 1939 World's Fair Necklace," which was centered around the 80-carat Empire Diamond.

She wore the jaw-dropping piece while attending her Oscars afterparty with husband JAY-Z at the Chateau Marmont, to which she also wore a barely-there Celia Kritharioti mesh gown with a waist-high slit and seductive sequin placements.

Later in 2022, the power couple – who share daughter Blue Ivy, 11, and five-year-old twins Rumi and Sir – were named ambassadors of the label.
