What is quarze?

Quartz is a mineral composed of silicon and oxygen atoms, often found in various colors and forms. It is the second most abundant mineral in Earth's continental crust, after feldspar. Quartz has a hardness of 7 on the Mohs scale, making it a durable and popular choice for jewelry and ornaments. Quartz can also have piezoelectric properties, meaning it can generate an electric charge when subjected to pressure or heat. This property makes quartz valuable in electronic devices like clocks, watches, and computers. Geologically, quartz is found in igneous, metamorphic, and sedimentary rocks, and can often signify the presence of valuable minerals like gold. Overall, quartz is a versatile and widespread mineral with many uses in both industry and everyday life.
