Quartz is one of the most common and widely distributed minerals on the earth's crust, belonging to the class of silicates. Its chemical formula is SiO2 (silicon dioxide), it comes in various shapes and colors, ranging from clear quartz or "rock crystal" to smoky quartz or rose quartz, depending on the impurities present during its formation. Quartz has a hardness of 7 on the Mohs scale, making it a durable mineral. It is commonly found in igneous, metamorphic and sedimentary rocks. Quartz is also a piezoelectric mineral, meaning it produces an electrical charge in response to mechanical pressure. This property makes it a valuable element in electronics and communication.
