Since the 1940s, scientists have developed thousands of applications for quartz and quartz crystals. Quartz crystals give functionality to all our modern technology: computers, cell phones, televisions, radios, security cameras, electronic games, ultrasound, to name but a few! Microchips made of pure silicon - a product of quartz crystals - are the brains of every electronic device in existence. From watches to calculators to satellites to computers, these small chips allow for the convenience that makes so many tasks easier! Photo: rough (natural) specimen from our crystal mine.
