Turquoise Pavilion). There are many tales attached to it, especially in indigenous cultures in the Americas. You can read a Hopi legend here, and a Navajo legend here (this latter one associates turquoise with the female spirit).
There is a folktale from Bhutan about an old man who finds a huge piece of turquoise on his land one day. He cheerfully walks down the road with it, and then quickly exchanges it for a horse, then the horse for an ox, then the ox for a sheep, sheep for a goat, goat for a rooster, and finally, exchanges the rooster for a song, and walks home singing to himself, perfectly content and happy. I label this story "old man destroys capitalism." It reminds me of some Jack tales, except the song makes more sense to me than magic beans. Some bands nowadays wish they could buy a song for a rooster...
Anyhow. Another story, this one from Tibet, also features an old man and a turquoise. In this one, an old man is left alone with his two daughters-in-law who use him as a slave. He manages to get a message to his daughter, who sends him a turquoise stone. The old man tricks both women in the house into believing that he will leave the stone to the one who treats him better, and lives out the rest of his life in peace. Before he dies, he hides the stone, and sends another secret message to his daughter, telling her where to look for it. A lovely father-daughter tale, but not a very good story for in-laws.
