A little girl found a pretty stone about the size of a canary bird’s egg. She had no idea what it was, so she took it to a jeweler, who eventually bought it from her for a dollar, although he too did not know what it was. The stone turned out to be an uncut diamond worth $10,000. The girl tendered back the $1 purchase price and sued to have the sale voided on the basis of mutual mistake. Should mutual mistake be a basis for recovery?
