A further reliable type of carbon often called graphite would be the chemically stable sort of carbon at space temperature and tension, but diamond is metastable and converts to it at a negligible charge less than Individuals disorders.
Coatings are increasingly employed to offer a diamond simulant including cubic zirconia a far more "diamond-like" look. A single this sort of compound is diamond-like carbon—an amorphous carbonaceous material that has some Actual physical Houses just like those from the diamond.
Clarity can be a evaluate of internal defects of a diamond named inclusions. Inclusions may be crystals of a international substance or A further diamond crystal, or structural imperfections like little cracks which will appear whitish or cloudy. The variety, dimensions, coloration, relative locale, orientation, and visibility of inclusions can all affect the relative clarity of the diamond.
