Layman's explanation: Quartz has been known since ancient times. It was referred to as krystallos by the Greeks, but this later became the generic term for crystal. The name quartz is derived from the German quarz (c. 1530 A.D.). Although quartz occurs in almost every geological environment including the United States, the U.S. is 100% import reliant on industrial quartz. The major import sources for 1997-2000 were Brazil, Germany, and Madagascar. Many varieties of gemstones are quartz, including amethyst, smoky quartz, and rose quartz. One of the uses for electronic-grade quartz crystal is frequency control in radios, televisions, and other electronic communications. Quartz sandstone is used for building and quartz sand is used to make sandpaper.
