This new exclusive photo – taken when Jolie debuted the ring at a private event at the Los Angeles County Museum of Art last week – shows off the stunning sparkler, which Brad Pitt designed for her in collaboration with jeweler Robert Procop.
“Brad had a specific vision for this ring, which he realized over a yearlong collaboration with Robert,” Procop’s team said in a statement. “He wanted every aspect of it to be perfect.”
Nice work, Mr. Pitt.
