diana's tiara. very associated with kate. she's worn it so maybe it will go to meaghan. >> the halo that kate wore is on display in a museum in australia. that's not even available. but prince charles gave kate a beautiful set of jewelry when she was married. a yellow diamond and white diamond bracelet and ring and earrings and she's probably getting tons of jewelry. go ahead and keep that. >> thank you. >> whether the jewelry is theirs or whether it is -- was it a personal gift, personally bought or considered part of the collection. i want to see the crown of jewels. but a lot of the pieces that you'll see today are privately owned by members of the royal family. >> this raises the question that some people are talking on the streets about how much money this wedding costs.
