The intense hardness of diamond in specified orientations causes it to be helpful in materials science, as in this pyramidal diamond embedded during the Doing work surface of the Vickers hardness tester. Diamond is the hardest material over the qualitative Mohs scale. To carry out the quantitative Vickers hardness check, samples of elements are struck using a pyramid of standardized dimensions employing a acknowledged force – a diamond crystal is useful for the pyramid to permit a variety of resources to become analyzed.
