Sorry, this answer is incorrect. Quartz is not a mineral found throughout the body rather, it is one of the most common minerals in the Earth's crust. Quartz is silicon dioxide. Small particles of this mineral make up sand. Larger crystals are sought-after gemstones. Impurities give quartz different colors, example are pink rose quartz purple amethyst, yellow citrine, or gray-brown smoky quartz. Quartz is very hard and used in the manufacture of sandpaper. Quartz is also used as crystal oscillator because is produces voltage in response to mechanical stress (piezoelectricity). It is part of wristwatches, microbalances, and radio transmitters.
