Diamonds and Toads

Diamonds and Toads or Toads and Diamonds is a French fairy tale by Charles Perrault, and titled by him "Les Fées" or "The Fairies". Andrew Lang included it in The Blue Fairy Book. It was illustrated by Laura Valentine in Aunt Louisa's nursery favourite.

In his source, as in Mother Hulda, the kind girl was the stepdaughter, not the other daughter. The change was apparently to decrease the similarity to Cinderella.

It is Aarne-Thompson tale 480, the kind and the unkind girls. Others of this type include Shita-kiri Suzume, Frau Holle or Mrs.Holle, The Three Heads in the Well, Father Frost, The Three Little Men in the Wood, The Enchanted Wreath, The Old Witch, and The Two Caskets. Literary variants include The Three Fairies and Aurore and Aimée.

Summary
A bad-tempered widow has two daughters; her older daughter is disagreeable and proud, but looks and behaves like her mother, and is therefore her favorite child; her younger daughter is sweet, courteous, and beautiful, but resembles her late father. Jealous and bitter, the widow and her favourite daughter abuse and mistreat the younger girl.

One day while drawing water from the well, an old woman asks the younger girl for a drink of water. The girl politely consents and after giving it, she finds that the woman is a fairy, who had disguised as a crone to test the character of mortals. As the girl is so kind and compassionate toward her, the fairy blesses her with a jewel or flower falling from her mouth whenever she speaks.

Upon arriving home and explaining why she had taken so long to her mother, the widow is delighted at the sight of gems and flowers falling out the girl's mouth, and desires that her favored eldest daughter must have the same gift as well. The elder girl protests, but the widow forcibly sends her to the well. The girl sets off but the fairy appears as a fine princess, and requests that the girl draw her a drink from the well. The elder daughter speaks rudely to the fairy and insults her. The fairy decrees that, as punishment for her despicable attitude, either a toad or a snake would fall from the rude girl's mouth whenever she speaks.

When the girl arrives home, she tells her story to her mother and toads and vipers fall from her mouth with each word. The widow, in a fury, drives her younger daughter out of the house. In the woods, she met a king's son, who falls in love with and marries her. In time, the widow is sickened by her older daughter, and drives her out, and she dies alone and miserable in the woods.

Commentary
The idea of having jewels fall from a virtuous person is a motif found in various other tales, as in the Italian Biancabella and the Snake.
