“Passengers” star Chris Pratt showed his affection for Anna Faris with an upgraded engagement ring. Faris flashed the diamond stunner on the Los Angeles red carpet premiere of the sci-fi thriller Wednesday. Faris didn’t divulge many details about the ring, but Us Weekly talked to a jewel about the style, potential price tag and more.

“Anna's ring incorporates three of the hottest trends in engagement rings: unexpected center shapes, a halo and micro-pavé style,” Diamond expert Michael O'Connor told Us Weekly Friday. “The micro-pavé is a technique that makes the entire setting shimmer with tiny set diamonds in platinum or white gold to camouflage the metal. The halo has a special meaning — it says ‘You're the center of my universe’ — and it's one of the most popular trends right now.”

O’Connor added: “The center oval diamond is of magnificent quality, color and size. It's about 6 carats, which would make the approximate value of the ring $250,000. Definitely a holiday sparkler!”

The “Mom” star, 40, gushed about the ring. “He just got me this ring. I know. Like two days ago,” she said, showing off her new bling to E! Online. “I look [at it] and I'm like, ‘I can't believe it either!’ He's an incredibly romantic man and I'm very, very lucky.” Pratt, 37, joked back: “She got me a tractor so we're kind of even!”

While it’s clear Pratt is in love with Faris, he wasn’t thrilled she took co-star Jennifer Lawrence’s side in their picture war. While promoting “Passengers,” Pratt cropped J-Law out of all their photos. It’s since turned into a game.

“I fully support Jennifer Lawrence,” she told Entertainment Tonight Online Wednesday. “I’m all for it. I adore her!”

Pratt, 37, was stunned. “I can’t believe you’re Team Jen,” he said. “I need some support. I thought you’d back me up!”
