Kim Kardashian‘s stunning 20.5-carat engagement ring is obviously big. It’s so big, in fact, that husband-to-be Kris Humphries was able to include several inscriptions on the inside of the sparkler. “It’s engraved, with two things from the Bible,” Humphries tells PEOPLE. “There’s one verse [Proverbs 31: 10-31] about the perfect godly woman,” he explains. “The other, [1 John 3:18] is about love. It took me … a few days to pick them out and research the perfect ones.” In the middle of the two passages is a third inscription, “K [hearts] K,” standing, of course, for Kris and Kim.
Before proposing, Humphries sought guidance from one of Kardashian’s closest friends, publicist Jonathan Cheban. “I know all her girlfriends but he’s her only guy friend,” the basketball star says. “I wanted to ask him what he thought. A while ago, I called him and told him, ‘I have to do this, I have to propose, I want to do this now!’” But he held out. “I was going to do it on a vacation we took but the timing wasn’t right,” he explains. “[So when] Kim was in Miami doing a QVC thing … Jonathan came to L.A. and we just hung out and talked about [the proposal]. We set some things up.” Not only did Humphries plan the proposal in advance; he picked up the engagement ring early, too. “I got the ring a while ago,” he admits. “I had it for a few weeks.” He must’ve had a good hiding spot!
