The Tereschenko Blue Diamond (Терещенко). 42.92 carat, pear-shaped. Its original owners were the Tereschenko's, a family of sugar magnates in pre-communist Russia. In 1915, Mikhail Tereschenko instructed Cartier to mount the gem as the centerpiece of a necklace containing a variety of fancy colored diamonds.
Though it seemed like a pretty piece of fiction created by James Cameron, it turns out that there was a diamond and sapphire necklace on board that fatal night, given to a young girl, Kate Florence Phillips, 20, by her married paramour, Henry Samuel Morley, 40.
