Quartz naturally vibrates at an exact frequency and contains piezoelectric properties, which means that when it is pressurized, it produces a small volt of electricity. The inverse of this is also true, so that when an electric current is passed through quartz, it vibrates, usually at 32,768 times per second.
Quartz is 100 percent a natural material made up of a white or colorless mineral. But, unlike natural stone, such as marble, granite, and soapstone, quartz countertops are categorized as a man-made product.
