See Kourtney Kardashian and Travis Barker's Dazzling Lorraine Schwartz Wedding Rings

Kourtney Kardashian and Travis Barker said "I do" with some serious bling!

PEOPLE can confirm that the wedding bands the stars exchanged vows with on their wedding day on Sunday, May 22, are custom Lorraine Schwartz pieces. (Schwartz is the Kardashian-Jenner family's longtime go-to jeweler, as she famously designed Kim Kardashian's engagement ring from ex-husband Kanye West.)

Barker, 46, previously worked closely with the jeweler to also design his now-wife's jaw-dropping engagement ring, which PEOPLE exclusively confirmed in October 2021.

"It's a flawless, beautifully cut diamond stone," Schwartz previously told PEOPLE of the ring the Blink-182 drummer gave to Kardashian, 43, when he popped the question at the Rosewood Miramar in Montecito, California.

Kardashian and Barker's weekend wedding marked the third time the pair have tied the knot.

The first time the couple sparked marriage rumors was on April 4 when they had a "practice wedding" at a Las Vegas wedding chapel. The spontaneous exchange of vows included an Elvis Presley impersonator as the officiant and took place in the middle of the night.

On May 15, the pair were legally wed at a California courthouse. A source told PEOPLE the wedding took place in preparation for their Italy nuptials — to make sure the wedding would be legal.

"They had to legally get married first ahead of their big Italian wedding, which is happening very soon," the source said at the time. "All the details are set and the whole family, including all the kids, are very excited."

Barker proposed to Kardashian in October 2021 on the beach in Montecito, California. The romantic moment saw the couple standing in a heart made of roses and candles. The proposal and a celebratory dinner with family afterward were featured on Hulu series The Kardashians.
