Mood rings are, without a doubt, one of the best symbols of the 1970’s. They were invented by Marvin Wernick, a jewelry entrepreneur who, through a remarkable chance of fate, happened to travel with a doctor friend one day to an emergency visit. He saw him apply a temperature-gauging strip to a child’s forehead, and realized that the same could be done for junk jewelry. Nothing like that had ever been done before, so he quickly designed and released the garish product to the public, and by the middle of the decade he had become a millionaire.
Each mood ring possessed a thermotropic crystal that changed color depending on body fluctuations and (supposedly) a person’s mood. Dark colors represented negative emotions, such as stress or anger, while light colors represented a sense of inner peace. This was extremely helpful, because otherwise a person might have had no idea that they were feeling sad and gone on to have a productive day filled with good company and exciting opportunities instead of moping around the house all afternoon.
