The Briolette of India, a colorless diamond weighing 90.38 carats.

The diamond has been in the possession of many historical figures including Eleanor of Aquitane, Richard I of England and Diane de Portiers. It was known to be in the possesion of Catherine of Medici when it disappeared for 400 years. In 1950 it reappeared when it was bought by the jeweller Henry Winston from an Indian Maharajah. It is now believed to be in the possesion of an unknown European family.
