This gives us yet ANOTHER reason to want to marry R-Patz. 

FKA Twigs is rumoured to be engaged to Robert Pattinson and was showing off her engagement ring at the Met Gala this week.

Jeweller Mark Keeney told RadarOnline: "FKA Twigs' ring looks to be a custom style, possibly vintage. It features a pear-shaped diamond, which looks to be between one and two carats, set in a French-set halo."

"Two round bezel-set diamonds are set vertically on the finger, for an art-deco inspired look that flatters the length and suits her avant-garde sense of fashion," he said.

He then continued: "The setting is most likely platinum, the favoured metal for art deco jewellery. Depending on the quality of the stones, this engagement ring could be worth between $40k-$100k."

Wow, we bet Kristen Stewart is slightly bitter… it's okay Kristen, we would be too. 

The pair could be set to get married soon as they apparently both want a low-key ceremony in London. He popped the question after six months of dating.
