The black orlov diamond, also called the Eye of Brahma, was stolen from a Hindu shrine by a monk. The gem was passed down to multiple female owners, many of whom took their own lives. At least two of the women who took possession of the black orlov lept to their deaths from a tall building. After the jewel was sold to a jeweler in New York, the curse is said to have been broken, which is good for future owners but does no good for the previous victims of the stones bad luck.

The Black Orlov Diamond, also known as the Eye of Brahma Diamond, weights 67.50 carats and was once part of a much larger uncut 195 carat diamond which can be traced back to 19th century India. Legend has it that the uncut stone originally featured as one of the eyes in a statue of the Brahma, the Hindu God of creation, which stood in a shrine in the southern city of Pondicherry. It is believed that here the diamond was stolen from the statue by a travelling monk after which it became cursed.

Whilst many are sceptical about the existence of such a curse and its beginnings are thought to be little more than folklore, the journey of the diamond from here on is still one shrouded in mystery, drama and death.
