Brad Pitt, Angelina Jolie Crystallize Love With Ring (photo!) 1Brad Pitt’s long desire to formally tie the knot with partner Angelina Jolie crystallized, literally, with his stunning, personally designed engagement ring.

The ring, which first came to public attention at a private event at the Los Angeles County Museum of Art last week is the handiwork of jeweler Robert Procop, who worked with Pitt for more than a year to create the piece.

“Brad had a specific vision for this ring, which he realized over a yearlong collaboration with Robert,” Procop said in a statement. “He wanted every aspect of it to be perfect.”

The large, square diamond is the centerpiece of the ring. It’s bordered by oblong-shaped diamonds inset into a ribbed band. “The side diamonds are specially cut to encircle her finger. Each diamond is of the highest gem quality,” Procop said.

Experts valued the ring at $250,000.

The Hollywood couple confirmed their engagement last week in a statement. Brad recently revealed that mounting pressure from their children caused them to rethink their plans about marriage.

“It seems to mean more and more to our kids,” Brad said in January. “We made this declaration some time ago that we weren’t going to [get married] till everyone can.” The couple ardently support same-sex marriage.

“But I don’t think we’ll be able to hold out … it means something to me, too, to make that kind of commitment,” he added.

Jolie has always been the one shy about getting married, but not about her commitment to Brad.

“We’ve explained to them that our commitment, when we decided to start a family, was the greatest commitment you could possibly have. Once you have six children, you’re committed,” she’s previously said.
