The only thing that can cut a diamond is a diamond. In other words, these diamond cutting and polishing tools have a certain lifespan, and after a certain period of time, they break down and can no longer be used.
Diamond powder is also sprinkled on the sand table to polish some of the diamond's facets. After all, diamonds other than gem-quality diamonds are industrial-grade diamonds and cannot be used to wear jewelry. Many silently participate in the manufacturing process.
Diamond is the hardest substance known in nature, with a Mohs hardness of 10, and all other minerals cannot wear diamonds.
The process of a diamond factory is divided into many links traditionally inseparable from the diamond as a cutting agent. An ideal natural rough diamond in the jewelry industry should be a regular octahedron. Although this crystal form is not the only form of natural diamond, this crystal form has the least loss in diamond processing and production
Lasers are also used to cut diamonds. The chemical composition of diamonds is carbon, and laser focusing can generate high temperatures to burn and gasify the carbon. Cutting diamonds with a laser actually burns off some of the excess carbon to achieve the goal of reshaping the rough diamond.
