The acute hardness of diamond in certain orientations causes it to be valuable in products science, as Within this pyramidal diamond embedded while in the Functioning area of the Vickers hardness tester. Diamond is the hardest content to the qualitative Mohs scale. To conduct the quantitative Vickers hardness check, samples of resources are struck which has a pyramid of standardized dimensions utilizing a acknowledged drive – a diamond crystal is utilized for the pyramid to permit a wide array of products to become examined.
Coatings are more and more utilized to provide a diamond simulant for instance cubic zirconia a far more "diamond-like" visual appearance. 1 these compound is diamond-like carbon—an amorphous carbonaceous product that has some physical Qualities similar to These of your diamond.
