Margot Robbie and the Taj Mahal necklace

Margot Robbie is known for promoting her films in full costume and her latest red carpet effort for Wuthering Heights is no exception. She turned up in a bespoke gown and a heart-shaped diamond necklace. When asked about it she said that it was 'the Elizabeth Taylor necklace', at which point the internet let loose with people pointing out it's 400 year history and that the diamond was originally a gift from 1600s Mughal emperor Shah Jahangir to his wife Nur Jahan.
