GEOLOGY: Clear quartz is a part of the quartz family so it is a silicon dioxide crystal. Quartz crystals exhibit the proper of piezoelectricity, meaning they can transform mechanical energy (e.g. pressure) into electromagnetic energy and vice versa. This property makes it useful for devices such as crystal radios, microphones, watches, radio transmitters etc.
ZODIAC: All signs but particularly useful for Leo's, Capricorns and Gemini's.
BORN IN: Worldwide, especially USA, Brazil, Madagascar.
