Jewelry at the Harry Potter Premiere

In typical British fashion, jewelry was somewhat understated at the Harry Potter and the Half Blood Prince world premiere in London. J K Rowling wore a huge pair of chandelier earrings and Helena Bonham Carter's dog tag pendants were engraved with the names of her children. Daniel Radcliffe was one of the cast members who wore a white wrist-ribbon in memory of Rob Knox, a young man who appeared in the film but was murdered in 2008.
