After 111 years, a necklace that was lost in the sinking of the Titanic has been found. Magellan, a company specializing in deep-water investigations, discovered the necklace while creating the first full-sized digital scan of the ship. The necklace is made of gold and a pre-historic Megalodon shark's tooth. Magellan used over 700,000 images from multiple angles to create an exact 3D reconstruction of the luxurious ship that sunk after striking an iceberg in 1912.
