Quartz Countertop Misconception #1: Quartz is scratch resistant! 

There is plenty of anecdotal information disseminated by interior designers and sales people highlighting Quartz as having Granite qualities (scratch resistant).

Fact: All Engineered Stones will indeed scratch and lose its appearance. The Quartz chips are scratch resistant, however the resin binder and other components are not. 

Although, Quartz or engineered stone uses pieces of natural stone during the formulation process, Quartz countertops are not Quartzites which is metamorphic rock  “formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures.” Whereas, Quartz or engineered stone is a blend or hybrid synthetic countertop formulated and baked during manufacturing. Quartz or engineered stone consist of stone chips, resins, and pigments.

It is easy to confuse Quartz as Quartzite. They are distinctively two different countertops.

Quartz Countertop Misconception #2: Quartz harder than Granite and Quartzite

How hard is Quartz? How hard is Quartzite? Good questions! Quartzite is more scratch resistant than Quartz or Engineered Stone.


Moh Scale of hardness

Most hard surfaces are rated based on the MOH scale of hardness. You may not be aware of this, Friedrich Mohs was a German mineralogist who developed his ground breaking scale in 1812. The scale is an example to show the hardest mineral to the softest.

For more information about Friedrich Moh’s scale of hardness, select or copy link below:  


Since Quartz is an engineered stone based on its formulation of minerals and substances, how hard is the Quartz chips? The Quartz chips would shares the same hardness characteristics. All of the others elements that make up Quartz's countertops such as glass, silica, plastics, glitter and resin (binder) are softer. 

Considering theses variables the Quartz countertop hardness might vary depending on its overall composition and formulation.

For example: 

  • Marble’s MOH scale of hardness is 3-4
  • Limestone and Travertine depending on the location it’s quarried will be close in hardness of Marble. 
  • Granite’s MOH hardness is 6-7
  • Quartzite is 6-7
  • Quartz’s MOH scale of hardness is approximately 5.5 - 7 depending on the manufactures mixture. 

The manufacture using any combination of the mineral would yield different MOH of hardness rating. The 70% or higher resin binder to make Quartz countertops would always be softer. In the examples above the resin binder is approx 4.4 on the MOH scale of hardness. 

How can Quartz countertops be scratched? The answer may surprise you. 

  1. Surface abrasion will create microscopic scratches. As theses micro scratches increase and widen the scratches will become more visible. In time, your Quartz countertop in these damaged area will ugly out requiring full restoration.
