12 Hardest Minerals Found The Earth (2023)
The earth's crust contains a large number of minerals. However, if we were to rank them according to their hardness, some minerals would be much harder than others. There are a few methods that can be used to determine how tough they are, like the Brinell scale and Vickers hardness test. However, the Mohs' Hardness Scale is the most widely used and reliable method.
