The image shows Kate Winslet with the amazing big sapphire pendant in the movie Titanic. The fact is that the blue gemstone pendant in the movie had neither sapphire nor diamonds. The movie used a big pedant that was mounted with a cheap factory made cubic zirconia gem stone. The diamonds that surrounded this blue cubic zirconia heart shape gem were not diamonds, they were once again cheap white zircons. The interesting thing is that this fake blue gemstone pendant from the movie Titanic spawned thousands of cheap look-alikes which were also made with fake gems. The story took an interesting turn when the jeweler that made the fake pendant for the movie, went on to make a REAL ceylon sapphire and diamond pendant cast in platinum. This stupendous big sapphire heart pendan was priced at over 3 million U.S$.
