This Indian stone was believed to hold magical powers and was usually worn as an amulet. The stone is black, about the same size as a billiard ball and pierced with holes. The stone is said to lie in the Gandaki, a river in Nepaul which is believed to rise at the foot of Vishnu. The stone is thought to be kept in a cloth and washed and perfumed regularly by its lucky owner. The water in which it is washed and dipped is believed to have the power to dispel sin, so it is often consumed and greatly valued. The water is also held in the hands of Hindus as they die, because they believe that it offers hope for the future.
