Behold, the Jolie-Pitt Diamond!

As reported at Us Weekly Friday, Angelina Jolie debuted an engagement ring from Brad Pitt in L.A on Wednesday.

With Pitt, 48, and son Pax, 8, at her side, the Oscar-winning actress, 36, clad in a white satin shirt, quietly flashed the bauble during a private viewing of the Los Angeles County Museum of Art's Chinese Galleries.

"I can confirm that, yes, Robert Procop did indeed design an engagement ring for Angelina Jolie, designed in collaboration with Brad Pitt," a rep for the couple's longtime jeweler Robert Procop told Us Weekly in a statement.

Procop acquired "a diamond of the finest quality which was then transformed using Pitt's unique designs, cut with distinctive faceting to a shape and size that perfectly suits Angelina's long, slender fingers," the rep explained.

"Throughout, Brad Pitt remained heavily involved, overseeing every aspect of the creative design process from the perfect cut of the diamond centerpiece - an elongated tablet shape - to the finishing touches such as the mounting of a galaxy of smaller stones which are graduated in size and faceted to match, adding a crowning lustre to the ring."

The process took about a year, the rep said. A rep for the couple could not be reached for comment.  Pitt waited for the "perfect moment to unveil this special jewel to Angelina Jolie," the rep explained.
