Britney Spears may be a pop-star diva to the rest of the world, but to beau Jason Trawick, “she’s his everyday princess,” says celebrity jeweler Neil Lane, who designed Spears’s dazzlingengagement ring to befit Trawick’s vision of the singer’s down-home regality. “Jason is a romantic and when I asked him to tell me about Britney and what the ring would represent to them so I could find inspiration, his response was always the same — she is his princess!”

With that theme in mind, Lane tells PEOPLE he designed from scratch a tiara-motif sparkler with a round, perfect white diamond in a handmade platinum setting that “looks like a mini crown,” the celebrated jeweler says. He also added 90 small round diamonds around the eternity band. “Jason didn’t want an over-the-top ring with a giant stone,” he adds.

Over the last month, Lane and Trawick clocked phone and email minutes as they collaborated while Trawick was traveling with Spears on her global tour. “Texts came from all over the world, from Abu Dhabi, Mexico and I don’t know where else!” says Lane.

But when Trawick stopped into Lane’s Los Angeles store to pick up the ring — less than one week before the proposal! — they both knew the hard work and scheming had paid off. “Oh my god, he loved it,” Lane shares, adding that he could tell Trawick had pre-proposal jitters. “The guy was so excited and nervous. At the end of the day, even with all the fame, he’s still a normal guy who was about to propose to the woman he loves.”

That said, Lane believes this couple is in it for the long haul. “He’s deeply in love with her. Britney is his princess and he is her knight in shining armor,” he says. “Jason’s protective of her. He adores her. Every good fairytale needs a princess, and now Britney has a ring fit for a princess!”
