Certain varieties of minerals are considered treasures not only because of their scarcity but also due to their inherent beauty. Moreover, it is believed that they possess healing powers in various cultures. Crystal radios tap into crystal's functionality as semiconductor, which transformed them into communication tools. A mineral radio is the simplest wireless receiving device. The first crystal radio was developed by Greenleaf Whittier Pickard in 1900, utilizing a bar-shaped mineral crystal to detect radio signals. Common minerals used as detectors include lead sulphide, galena, iron pyrite, silicon, molybdenite, and silicon carbide, etc, which convert radio signals into audio signals. With technological improvement, crystal radios have gradually been replaced by more advanced semiconductor devices such as transistor radios and integrated circuit radios.
