Diamonds form only about 100 miles below the surface of the earth at high temperatures and pressures.A diamond's carbon atoms bond essentially the same in all directions.Another mineral, graphite, also contains only carbon, but its formation process and crystal structure are very different.Graphite is so soft that you can write with it, while diamonds are so hard that two diamonds cut each other and only scratch.So what's the hardness of the diamond, what's the mohs of the diamond.

The hardness of diamond is 10.Hardness, the physical term for the ability of a material to resist locally pressing a hard object into its surface, is called hardness.Moss USES the scratch hardness of 10 minerals as a standard to determine 10 hardness levels, known as mohs.The order of mohs hardness of 10 minerals is: diamond (10), corundum (9), topaz (8), quartz (7), feldspar (6), apatite (5), fluorite (4), calcite (3), gypsum (2), talc (1).Among them, diamond is the hardest and talc is the softest.Mohs hardness standards are arbitrary and cannot be used precisely to determine the hardness of a material. For example, the actual hardness difference between grades 10 and 9 is much larger than the actual hardness difference between grades 2 and 1.But this classification is very useful for mineralogists working in the field.Because diamonds are the hardest, they must be cut and machined using either diamond powder or a laser.

Diamond can be divided into industrial grade diamond and gem grade diamond according to use.

Industrial diamond processing into a variety of diamond tools used in industry, it does not require the color of the diamond, clarity, mainly to use the hardness of the diamond and its special properties, so as long as the diamond can be processed into different diamond tools are used, its price is cheaper.
