Diamond is a mineral composed of pure carbon and is the hardest naturally occurring substance in nature. Its chemical formula is C. It belongs to the equiaxial crystal system and is characterized by high hardness, high melting point, high insulation, chemical stability and resistance to acid and alkali corrosion. The formation conditions of diamond are extremely special, requiring extremely high temperatures and pressures in the depths of the earth, the formation of extremely strong and regular arrangement of carbon atoms between the structure, this structure gives the diamond its unique physical and chemical properties.

Physical Properties: Diamond has a hardness of 10 degrees on the Mohs scale, a density of about 3.52 grams per cubic centimeter, a refractive index of 2.4175 to 2.4178, and a dispersion value of 0.044, which enables diamond to display colorful flashing effects. Pure diamond is colorless and transparent, but when it contains different impurities, it can show a variety of colors such as yellow, blue, pink or green. The common crystal forms of diamond include octahedron, rhombic dodecahedron and cubic, with inverted triangular concave pits sometimes visible on the crystal surface. After the formation of crystals, they are subjected to solvation, which makes the crystal surface convex to form convex crystals, and the crystals tend to be spherical.

Chemical Properties: Diamond has a very high chemical stability, almost not subject to the corrosion of ordinary acids and alkalis. Its formation conditions determine its internal structure is very stable, there are no free electrons, and therefore does not conduct electricity. These properties of diamond enable it to have a wide range of industrial uses, such as the production of advanced abrasive materials, cutting tools, drills and wire drawing dies.

Uses: In addition to being used in industry because of its extreme hardness, diamond is also loved for its beauty and rarity as it is processed into a variety of jewelry, such as diamonds. The constancy and brilliance of diamonds make them one of the most popular gemstones.
