Justin Theroux proposed to his now-fiancee Jennifer Aniston with a striking 8-carat diamond ring, and the actress says she's thrilled with her beau's design.
"I was impressed," Jennifer told People of her blinding bauble. "I had no idea what I wanted. He just knows what I like."
To get a feel for the actress' jewelry taste, Justin enlisted the help of Jennifer's trusted stylists for guidance.
"[He] worked with the girls that I have worked with for years and years and years, so he kind of was picking the specialists' brains," she told the mag. "He kept it within a very small circle of people. It was one of the sneakiest jobs I've ever seen, actually."
The actress was completely caught off guard by her "Wanderlust" co-star's proposal - something Jennifer said is nearly an impossible feat.
"It's hard to pull one over on me, where I'm not like, 'Hmm, you're acting really strange,'" she said. "It was... a very covert operation."
The couple became engaged in August, on Justin's birthday.
"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," a rep for Justin told Access Hollywood at the time.
