People.com Lifestyle Style Kim Kardashian Shows Off Flashy Diamond and Opal Grill in KKW Beauty Lip Kit Campaign Kim Kardashian's custom grill was made with her birthstone, opal By Kaitlyn Frey Kaitlyn Frey Instagram Twitter Assistant Style & Beauty Editor, PEOPLE People Editorial Guidelines Published on May 17, 2021 05:53 PM Share Tweet Pin Email Photo: Kim Kardashian/Instagram Kim Kardashian doesn't wear grills very often, but when she does it always becomes an instant fashion moment. The style and beauty mogul, 40, has dabbled in diamond grills and flaunted the different designs on social media. But she hasn't shared a close-up look at one of her favorite, flashiest accessories in a few years, until now. Kardashian dressed up her look in a KKW Beauty campaign to promote the brand's 3-piece lip kit sets by wearing a custom diamond grill accented with opals (the star's birthstone). She filmed a few clips of herself wearing the grill and posted them to her Instagram Story. She also popped on a different grill on her top set of teeth and laughed while she made a face showing off the gold covering to the camera. Kim Kardashian/Instagram Kardashian first revealed the newest addition to her grill collection in March when she shot the KKW Beauty lip kit campaign. "New opal birthstone grill alert," she wrote on Instagram.

The KKW Beauty mogul also modeled her "KIM" diamond grill to promote her new lip launch. The design is one she first debuted to fans in 2018. For many years, Kardashian toned down her look (which included scaling back on her diamond accessories) after getting robbed of $10 million worth of jewelry at gunpoint in Paris in Oct. 2016. While a source had told PEOPLE that while the 2016 incident "irrevocably" changed her, Kardashian "is still going to be herself" — which means getting glam when she's in the mood. "She was toned down and out of the public eye after the robbery, but eventually she realized she needs to live her life," the insider said in 2018. "She has fun with fashion and style, and yes, it's part of her image — to be glamorous and push boundaries. So she's going to do it."
