Quartzite vs Quartz | Aria Stone Gallery

While their names are quite similar, there is a big difference between quartzite and quartz. The main difference being that quartzite is a natural stone and quartz is a man-made stone composite. Read along to compare the differences between quartzite and quartz.

  • Quartzite is a natural stone that is extracted from the earth.
  • Quartz is an engineered (man-made) composite, meaning that they crush up quartz and mix it with a polymer to create a slab.

Which is more stain resistant: quartz or quartzite?

  • Quartzite, due to its natural makeup, may stain if not sealed properly.
  • Quartz isn’t prone to staining due to the polymer chemical blend.

All quartzite is different in terms of porosity and stain resistance as it depends on how tightly the minerals bonded together during the mineral metamorphic process. In general, quartzite such as Sea Pearl and Taj Mahal have highly bonded minerals, while Macaubas may have been exposed to less pressure, making it more porous and prone to staining. Avoid staining from household items by using a sealer, which is typically provided by the installer or fabricator. To maintain this coverage, we recommended to seal your quartzite about once a year with a home application sealer.

Which is more heat resistant: quartzite or quartz?

  • Quartzite is generally resistant to heat warping; however, we would always  recommend using a trivet to protect your countertops from extreme heat of pots and pans – just in case.
  • Quartz is generally not heat resistant due to the polymer that can change shape when in contact with extreme temperatures.

Does quartzite or quartz scratch?

  • Quartzite is incredibly scratch resistant due to its dense mineral composite. While the mineral composite can vary throughout natural materials, most quartzite does not scratch. In fact, it measured around a 7 out of 10 on the Mohs Hardness Scale, as compared to granite, which rates as a 6.
  • Quartz is susceptible to scratching due to the chemical makeup of polymer.

Does quartzite or quartz etch?

Neither quartzite or quartz are prone to etching. And if you cook frequently and want to make sure that your countertops are safe from etching, then you might want to consider quartzite. Quartzite will not etch from acids found in household items such as vinegar and lemon juice. However, both quartzite and granite will react to hydrofluoric acid, which is found in some rust removers. Thankfully, hydrofluoric acid is not a common ingredient in household products.

Is it harder to clean quartzite countertops than it is to clean quartz countertops?

No, the cleaning process for quartzite and quartz is the same. Clean both quartzite and quartz using a soft, wet cloth and regular soap. Neither should be cleaned with abrasive cleansers. Learn more on how to clean your natural stone.
