A platinum and diamond necklace recovered from the Titanic is seen in an image made from video. This piece and others begin a three-city tour in Atlanta on Friday, Nov. 16, 2012 and represent the largest collection of jewelry ever on display marking the 100th anniversary of the sinking of the ship. Although single pieces of jewelry have been on display at one or more permanent and traveling exhibits sponsored by Premier Exhibitions Inc., their Atlanta debut is the first time the majority of the collection has been available to the public.
