Wrong! The correct answer is mountain of light.
Kohinoor means 'mountain of light'. Its history dates back to 1304. The stone was initially owned by the Rajah of Malwa, but was seized by Nadir Shah of Persia, after he successfully tricked the emperor into switching turbans with him as a part of the old oriental custom.
The diamond then reached Persia and remained there till the fall of the empire.
After the British annexed Punjab, they took possession of it. In Britain, its size was cut down to 108.93-carats from 186-carats to restore its brilliance and luster.
Queen Elizabeth wore the Kohinoor studded tiara in 1937 for her coronation ceremony. The diamond is kept in the Tower of London.
