Benny Blanco's wedding ring features his and Selena Gomez's birthstones

Luxury jeweller Jacob + Co. created the one-of-a-kind 18-carat gold wedding ring, which featured the couple's wedding date engraved on the inside, with a 0.03 carat round pave ruby and a similar-sized pave aquamarine - Selena and Benny's birthstones respectively - also on the inside of the band.

The firm also created a watch and bracelet for Benny to wear on the big day.

Jacob + Co. CEO Benjamin Arabov said in a statement: "Jewellery tells a story, and with these bespoke creations, we wanted to capture Benny and Selena's love in its purest form.

"Every detail down to the choice of stones, was meant to honour their journey and create heirlooms that will last forever. We are proud to be part of this journey."

The 33-year-old bride announced her marriage by sharing a number of photos and video clips from their big day.

The post was simply captioned with the date, which had two white heart emojis either side.

The post included a clip of Selena straightening Benny's bow tie before giving him a kiss, and photos of him lying with his head in her lap as she sits on the ground, the newlyweds embracing, a close-up of the bride's white flowers and another of her rings.

Among those expected to be in attendance for the wedding were Taylor Swift, Paris Hilton, Ed Sheeran, and Selena's Only Murders in the Building co-stars Steve Martin and Martin Short.

The happy couple both wore Ralph Lauren, with Benny in a black tuxedo and his new wide in a white dress with a halter-style bodice, floral detailing and an open back.

Selena recently praised Benny - who proposed to her last December - for helping her to feel "very normal".

She told Allure: "I appreciate his heart, his kindness, his quirks ... He's one of the most grounding people in my life, and he makes me feel very normal."

Although the pair were friends long before they got romantically involved, the brunette beauty doesn't think she'd have been "mature enough" to have dated Benny until the last few years.

Speaking about her personal evolution, Selena explained: "I don't think I would have been remotely mature enough.

"It's weird to think that only five years ago I wouldn't have been in the right place, but I've learned so many lessons [since then] that led me to being the best partner I could be for Benny. And I believe the same with him.

"He'll say, 'Gosh, why did we waste so much time?' And I always say, 'You wouldn't have liked me back then.' I was all over the place."
