Question

Quizplus · Accepted Answer

Diamond is the hardest known natural material on the Mohs scale of mineral hardness, where it is given the maximum hardness rating of 10. Traditional hardness testers like the Brinell, Rockwell, and Vickers are designed for metals and do not have the capability to accurately measure the hardness of materials as hard as diamond. These methods are not suitable for testing the hardness of diamond, as they rely on the indentation of the material under a specific load, and diamond's extreme hardness means that it would not be indented by the indenters used in these tests.
