Some films go down in history for acting, directing, Oscar wins or box office records. Others forever have a special place in our minds thank to the truly dazzling jewelry moments that appeared on-screen. We can’t think of Marilyn Monroe’s Lorelei Lee in 1953’s Gentlemen Prefer Blondes without remembering her drenched in diamonds. The “The Heart of the Ocean” necklace in the 1997 classic Titanic stole every scene despite its starry cast.
