6) The Pink Legacy - $50.7 million

On November 13, 2018, the Pink Legacy Diamond was sold at Christie’s in Geneva. This 18.96-carat diamond was bought by Harry Winston and was instantly renamed 'The Winston Pink Legacy'. The pink diamond came all the way from the mines of South Africa and was once owned by the famous Oppenheimer family. Not only is it one of the most expensive jewelry items, but is also one of the rarest in terms of grading.
