A source exclusively tells E! News that the actress' stunning bracelet, featuring five rows of sparkling white quartz, was a Christmas gift from Pitt in 2011—a present that the architecturally inclined actor helped design along with Jolie's personal jeweler, Robert Procop.
While she may have worn the bauble to more private affairs since, Tuesday marked her first time showing it off in public.
And the romance didn't stop at Jolie's wrist. The diamond earrings she was wearing were also a recent gift from Pitt, designed to match her engagement ring.
Both of Pitt's creations, meanwhile, were based on an original tablet design first used by Jolie when she had a pendant made for her real-life leading man. The tablet has since been a running theme in their presents to one another.
Jolie has since decided to add Pitt's bracelet design to her Style of Jolie jewelry collection, which will be available in September at Y2 jewelry boutiques in China and a few select retail stores in the U.S. The earrings the actress wore to WWZ's Paris premiere were part of her collection, sales from which will benefit her Education Partnership for Children of Conflict foundation.
And we'll be keeping our eyes peeled: We don't have the specifics yet, but another source tells us that Pitt also gave Jolie jewelry for her 38th birthday yesterday.
No doubt it's stunning.
