Quartzite is a hard, metamorphic rock that originates from sandstone. It forms through the process of diagenesis and metamorphism, where sandstone is subjected to high heat and pressure, causing the quartz grains to recrystallize and bond tightly together. This results in a dense and durable rock that is often used in construction and landscaping. Quartzite is characterized by its varied colors, often featuring intricate patterns and a natural luster, making it a popular choice for countertops, flooring, and decorative stonework. Its resilience to weathering and scratching enhances its appeal in both indoor and outdoor applications.
