Jionni LaValle put a $55,000, 5-carat ring on Snooki's finger. (Check out the photo on the left)

The jeweler who made it says Jionni proposed at the W Hotel in Hoboken, New Jersey, and he did it the old-fashioned way . . . quote, "Jionni got down on one knee on the balcony.  Snooki had no idea that she was getting an engagement ring."
