Robert Pattinson and FKA twigs turned heads on the 2015 Met Gala red carpet, but they were nearly outshined by her gorgeous engagement ring.

The "Video Girl" singer, 27, was first spotted wearing the bauble in April. E! News recently spoke with a diamond expert to find out more about the dazzling engagement ring.

"FKA Twigs is sporting a highly stylized bow shaped ring featuring a pear shaped diamond of approximately 4 carats with an approximate value of $150,000," Morgan Shara of MASbisjoux jewelry told E! News. He added that it's "quite the unique setting for quite the unique lady."

It was previously confirmed in early April that the 27-year-old actor and the "Pendulum" crooner were engaged after dating for eight months.

Whether or not Pattinson and FKA twigs were ready to announce their engagement, her friend T-Pain spilled the beans during an April 1 interview with Vulture, in which he said, "She's engaged now, so that's about to be a whole other thing."

When the interviewer asked, "Wait, she's engaged?" the rapper responded, "Yeah, to ol' Patty. I don't know if she wanted anybody to know that."

While the relationship is moving too fast for some fans, the couple shares so much in common through music, art and interests that marriage is a natural next step.

"There is a special connection between the two of them," a source told E! News. "Music is a big part of the relationship, because it means to much to them. They clicked instantly and they literally have been inseparable."

Details are beginning to surface about the upcoming wedding. The couple plans to have a "bangers and mash" wedding in London this August. The British singer plans to wear something "fun and a bit different" rather than a traditional white wedding dress.

There is also talk of Pattinson wanting a prenuptial agreement.
