Diamond pyramid hardness (DPH) is a measurement of a material's hardness, equal to the value of the load divided by the surface area of the indentation. In practice, this area is calculated from microscopic measurements of the lengths of the diagonals of the impression. This testing can be used for all metals and has one of the widest scales among ...

The hardness of diamonds has everything to do with how they’re made. Diamonds are made of carbon, but, contrary to popular belief, they don’t come from coal. Instead, they are formed deep in the earth’s mantle.

The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units.

Diamond scored a perfect 10 on this scale, clearly indicating that it is the hardest natural material when subjected to scratching. To understand how good a diamond is, consider steel, which is known for its toughness, scoring only a 4.5 on this scale!

Hardness and crystal structure. Known to the ancient Greeks as ἀδάμας (adámas, 'proper, unalterable, unbreakable') and sometimes called adamant, diamond is the hardest known naturally occurring material, and serves as the definition of 10 on the Mohs scale of mineral hardness.Diamond is extremely strong owing to its crystal structure, known as diamond cubic, in which each carbon atom ...

Diamond is the hardest known natural material on both the Vickers scale and the Mohs scale. Diamond's great hardness relative to other materials has been known since antiquity, and is the source of its name. This does not mean that it is infinitely hard, indestructible, or unscratchable.

The hardness of diamond is due to the structure of its carbon atoms. Diamond is a giant Covalent Structure, made only from carbon atoms. Each carbon atom forms 4 covalent bonds in a very rigid structure. This makes Diamond the hardest substance known to man.

If the conditions are just right, carbon atoms can form a solid, ultra-hard structure known as a diamond. Although diamonds commonly known as the hardest material in the world, there are actually...
