Gemstone Hardness: The Definitive Guide at AJS Gems

In gemology, gem hardness is measured on a scale known as the Mohs scale, which assigns minerals a value between 1 (softest) and 10 (hardest). This scale was devised by a German mineralogist, Frederick Mohs, in 1822. It defines hardness in terms of scratch resistance, where a harder mineral will scratch a softer one, but not vice versa.

Granite Hardness: How Hard is the Natural Stone?

Sep 05, 2019The hardness of any mineral is rated on a 1 to 10 scale called the Mohs scale. This scale was invented by German mineralogist Friedrich Mohs in 1812, and ranks minerals based on their ability to scratch or sustain scratches. A ranking of 1 means the mineral is very soft, while a ranking of 10 means it is very hard. What is the Hardness of Granite?
