Angelina Jolie is wearing an engagement ring, according to jewelry designer Robert Procop, reports The Hollywood Reporter. Procop said that he worked with her longtime beau Brad Pitt to develop the multi-diamond design to fit perfectly on Jolie’s finger. ”Brad had a specific vision for this ring, which he realized over a yearlong collaboration,” Procop said. As for how Procop scored the high-profile clients? Jolie currently designs her own collection for the Beverly Hills jeweler, The Style of Jolie, sales of which are donated to building schools in Afghanistan. The pair have been together since 2004, and have six children.
