The Beauty Stone is an opera, billed as a "romantic musical drama" in three acts, composed by Arthur Sullivan to a libretto by Arthur Wing Pinero and J. Comyns Carr. The medieval Faustian story concerns an ugly, crippled girl, who dreams of being beautiful and meeting a handsome prince. The Devil offers her a magical stone that confers perfect beauty to anyone who wears it. The stone is passed from one character to another, but eventually the prince recognizes the girl's beautiful soul, the stone is discarded, and the disappointed Devil leaves the town.
