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.

A few jewelry making pliers, a little bit of epoxy and a small batch of old costume jewelry -- that's all it takes to turn styles you don't wear into fresh, new designs. Mix and match components, and if you don't like what you create, take them apart and do it again.

A natural ruby can be expensive, but you don't have to buy a ruby to wear drop-dead gorgeous red jewelry. So if red gemstones are your thing, but a ruby's out of the question, it's time to explore the affordable alternatives. Other gemstones can fill your need for crimson.

Held just a few days after Michael Jackson's death, it wasn't surprising to see the BET Awards converted into a tribute for the King of Pop and his music. BET Awards jewelry was dramatic, and circular motifs were among the most popular trends. Amerie's big-link necklace is one of my personal favorites, and I like the goth-and-heart piece that Elise Neal wore.
