Megan Fox, 36, was one of the best-dressed stars at the Vanity Fair Oscar Party on March 12 — but she appeared at the event without her stunning $400K diamond and emerald engagement ring, which you can see close up in the pic and video below. The missing eight carat sparkler was created by celebrity jeweler George Khalife and according to him, designed to “symbolize two coming together to become one” with a pear-shaped emerald and matching diamond. In additional photos you can SEE HERE via Page Six, the Transformers actress wore a plunging black velvet gown that highlighted her thin figure. She notably had a huge diamond ring on her right forefinger, but her left ring finger remained unadorned.
