The only name garnering as much chatter as Brad Pitt and Angelina Jolie right now is Robert Procop – the man behind the actress’s engagement ring.

After a rep confirmed on Friday that Pitt and Jolie will tie the knot, the Internet was buzzing about Procop, who worked with the Academy Award winner, 36, on her “Style of Jolie” jewelry line last year.

Now everyone knows that Procop – who has shops in Beverly Hills, Geneva and Hong Kong – collaborated with Pitt, 48, for a year on creating the beautiful bauble. But here are some additional things to know:

1. Procop’s Beverly Hills store is open by appointment only
Procop’s Los Angeles shop is located on Dayton Way and Rodeo Drive, right in the heart of 90210. But that doesn’t mean it’s easy to find. Tucked away in a private location, an address to the place is not given freely over the phone. The designer sees clients on an appointment-only basis.

2. His jewelry is also worn by Robert Downey Jr.‘s wife
The actor’s better half, Susan, stepped out this week at the L.A. premiere of The Avengers, sporting amethyst jewelry made by Procop in honor of their new son Exton’s birthstone. At the 2011 Oscars, she also wore earrings Procop designed with Jolie.

3. His jewelry success paid his way through college
Procop’s teenage years were spent buying and selling diamonds. He became so well established as a gemstone trader that he was able to afford his university studies all on his own. He went on to open his Beverly Hills shop during his final year of school.

4. He calls it an honor to work with Jolie

“Angelina embodies sensual elegance, serene confidence and incomparable spirit,” Procop says in a statement on his website. From one endeavor, her creative vision draws two equally impressive outcomes: to transform the finest gems into transcendent works of art, and ultimately, to improve the lives of many who are in need.”

5. He’s charitable
For years, Procop has been involved in the L.A.-based non profit the House of Ruth, which helps families affected by domestic violence. According to his website, Procop bought and developed two shelters for the charity. The jeweler also “unequivocally supports Angelina Jolie’s charitable efforts helping children living in regions of conflict around the globe,” says the site.
