Quartz Category
Quartz is a highly durable mineral composed primarily of silicon dioxide (SiO2) and ranks second in abundance among Earth's minerals. Its crystalline structure results in exceptional hardness, scoring 7 on the Mohs scale, making it ideal for use in electronics, timepieces, and glass manufacturing. Varieties of quartz, including amethyst, citrine, and rose quartz, are prized in jewelry and ornamental applications owing to their diverse colors and clarity. The mineral's resistance to weathering ensures its widespread presence in sedimentary rocks and beach sands across the globe.
