Rihanna walked the blue carpet at the Smurfs premiere with her two children, RZA and Riot, in Los Angeles. The star’s two adorable kiddos nearly stole the spotlight, but RiRi had another beautiful accessory with her that wowed those in attendance.

Fans couldn’t help but notice the “Umbrella” hitmaker‘s stunning ring on her left hand.

Here are the details on Rihanna’s look and that rock with a price tag that will make your jaw drop.

Rihanna, RZA, and Riot’s looks at the ‘Smurfs’ premiere

The actress and singer, who is expecting her third child with partner A$AP Rocky, looked amazing on the blue carpet at Paramount Pictures Studios donning a figure-hugging brown gown. The proud mom was wearing a dress by Saint Laurent’s creative director Anthony Vaccarello from the brand’s fall 2025 ready-to-wear collection.

According to WWD‘s review of the collection, “The fall collection packed a wallop with its rich palette; sophisticated color combinations immediately recognizable as YSL, like ochre-khaki or orange-purple; commanding shoulders, and a low-slung waistline which tied a neat bow on the ’80s trend that’s been percolating through Paris.” 

The dress featured delicate lace detailing at the bodice, and flowing fabric cascading beneath a deep olive green bow, as well as a drop-waist silhouette that showcased her baby bump. Rihanna added some edge to her look with a sleek black leather jacket over the gown. She sported a pink lip and soft eye makeup to complete her look.

As for her children, RZA and Riot both wore custom-Dior looks for their first carpet appearance. Riot also had Dr. Martens 1461 Softy T Leather Oxford shoes in black paired with his outfit. 

Rihanna admitted that it was a bit of a struggle to get them both ready, sharing: “It was getting them dressed and undressed, dressed and then undressed again ’cause they wanted to eat, lay down, tumble … the last thing I did was get them dressed and then jump into my gown.”

The staggering cost of Rihanna’s ring

Rihanna had on some amazing jewels to go with her dress and it was hard to miss the impressive amber ring on her left hand. The jewelery and diamond experts at the U.K. retailer Steven Stone took a closer look at Rihanna’s huge rock to determine how much it cost.

Maxwell Stone told Showbiz Cheat Sheet: “While it has not been officially confirmed, after carefully examining numerous photographs, I am quite confident that Rihanna was wearing the stunning Pistil ring by David Webb at the Los Angeles premiere of the new Smurfs film.”

He continued: “The impressive statement piece showcases a large, oval-cut faceted amber gemstone, which is estimated to be approximately 10 carats in size. Surrounding the vibrant amber centrepiece are exquisite marquise-cut diamonds that add a dazzling touch of elegance and sophistication. The band itself is meticulously crafted from a combination of 18k yellow gold and platinum, with distinctive bursts of black enamel artfully incorporated into the design, creating a striking contrast and enhancing the ring’s bold, luxurious appeal.

“Retailing at $88,000 the Pistil ring exemplifies David Webb’s signature blend of artistry and craftsmanship, making it a true standout on Rihanna’s red — or in this case, blue — carpet ensemble.”
