The Mohs scale was developed in 1812 by a German mineralogist named Freidrich Mohs. It is one of the ways in which the hardness of minerals is measured. The scale includes ten readily-available reference minerals, ranked from 1 to 10 by their hardness.
The Mohs Scale of Hardness was created in 1812 by German geologist/mineralogist Friedrich Mohs. This method of hardness judgement is based on the ability of one sample of matter to scratch another. So a mineral ranked 8 out of 10 is harder and will scratch a mineral ranked 3.

A scale used to measure the relative hardness of a mineral by its resistance to scratching. From softest to hardest, the ten minerals of the Mohs scale are talc (measuring 1 on the scale), gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum, and diamond (measuring 10 on the scale).
On the Mohs scale of hardness (1-10), with 10 the hardest, granite measures between 6 and 6.5; whereas quartzite measures around 7. However, there is a chance for etching to occur on its surface. Quartzite is considered an exceptional material for use in countertops.
