Famous Indian diamond with a history dating perhaps as far back as the 14th century.
Originally a 191-carat stone that lacked fire (flashes of colour), it was recut to 109 carats in 1852 in an attempt to enhance its fire and brilliance. The Koh-i-noor (Hindi for "mountain of light") was acquired by the British in 1849 and became part of the crown jewels of Queen Victoria. It was incorporated into the state crown fashioned for Queen Elizabeth, consort of George VI, at her coronation in 1937.
