The precious things mentioned in the story are: the leaden heart of the Happy Prince and the dead bird. They are precious because they are generous and kind. The Happy Prince sacrificed the ruby of his sword so that the poor seamstress could get her son’s fever treated. He even went on to sacrifice his sapphire eyes and became blind. He kept giving away the gold leaves of his statue to be helpful to the poor and needy. The bird sacrificed his wish of going to Egypt with his friends and stayed with the Happy Prince instead. He ultimately sacrificed his life to help people and stay with the prince.
