Quartzite is a very hard metamorphic rock that originated as sandstone. Through a process of high heating and pressurization sandstone is transformed into Quartzite, an extremely strong and durable natural stone. When heated, individual quartz pieces recrystallize giving it a beautiful and decorative sparkling pattern. Quartzite is ideal for any countertop surface due to its strength and long-lasting composition. Consider quartzite countertops for its strength, beauty, and overall durability.
