To me, I normally acknowledge Thurday's at the night for Vampire Diaries.  What is so great about Thursday night this year is, right after Vampire Diaries, is Nikita.  But I'm getting ahead of myself here.
Vampire Diaries has become a hit TV show, and one piece of fashion that plays an important key are necklaces.  First with Elena's necklace, the one filled with vervain, and Bonnie's witch necklace.  I couldn't find the exact necklaces used in the show, but I have found a few that could pass.
