The Kohinoor Diamond is one of the most famous diamonds in the world. The Kohinoor diamond was first mentioned in 1306 when it was taken from a Rajah of Malwa, whose family had held the diamond for centuries. It was described as weighing 186 carats and was an oval cut white diamond - the shape and size of a small hen's egg. The Kohinoor diamond belonged to various Indian and Persian rulers but it became part of the Crown Jewels of England at the time that Queen Victoria was proclaimed empress of India. The Kohinoor was re-cut at this time and now weighs 108.93 carats and is kept in the Tower of London.
