Is this why Nick Jonas had to shut down a Tiffany & Co in London to get the right engagement ring for Priyanka?

By now, the news that Priyanka Copra is getting married to Nick Jonas has sunk in. Since then, we have been reading a lot of updates about this October wedding. People.com even reported that Nick shut down a Tiffany & Co. in London to buy the right engagement ring for PC in utmost secrecy. Well, can you blame that guy? Priyanka had set such high standards for him, we are sure he wanted to pass that test. Yes, in an interview with Elle, the actress had mentioned what her guy has to do to fetch the right ring for her. That's because he will be competing with none other than her father Ashok Chopra himself..
The video has PC showing off the 7-carat diamond ring given to her by her father. She says that it got her into a lot of trouble. She also mentions how any guy who wants to marry her has to 'top that'. From whatever little we could make out from the video, it looked pretty neat. Guess that's why Nick wanted everything to be absolutely right for his engagement and he got it right. Didn't she already say yes to the proposal?.
