Jonathan Arndt has commanded a reputation for its breathtaking jewelry thanks to its many appearances on red carpets over the years. The attention to detail and exquisite design is evident in every piece, created by this Beverly Hills-based brand. More recently the design duo behind Jonathan Arndt have been catapulted into the spotlight thanks to their close relationship with Grammy award-winning Country music star Carrie Underwood, with whom they also collaborated on the design of "The Heartbeat" necklace, featuring Burmese Rubies and a flawless yellow diamond, which debuted on the 2016 Grammy Awards red carpet.
