Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, white to gray with reddish-brown iron oxide veins, non-foliated crystal structure.
Formation & geological history
Formed through the metamorphism of quartz-rich sandstone under intense heat and pressure over millions of years.
Uses & applications
Extensively used in high-end construction for kitchen countertops, flooring, wall tiles, and decorative surfaces.
Geological facts
Quartzite is extremely durable, highly resistant to scratching, etching, and heat, making it harder than granite.
Field identification & locations
Identified by its crystalline sparkling surface and inability to be scratched by a steel blade. Commonly quarried in Brazil, India, and the USA.
