A cock was scratching the ground with his claws looking for a tasty morsel  to eat. While doing so, he chanced to turn over a stone and find a shining  gem under it. "Cock-a doodle-do !" Cried the cock and said, "It looks very fine and it may  be valuable to some people. but I would rather have found a nice grain of  corn." 
Gems can't pacify hunger.
