Diamond is the hardest natural material. It is the top hard material at Mohs Scale and has 10 of 10 rating. Diamond is familiar to people from thousand of years but its “wok carrier” started in 20th century when 2 major discoveries were made.
1. People started mining so called “Industrial Diamonds” or diamonds that don’t meet the requirements of quality or size to become gemstones. These diamonds became essential part of Industry performing specific tasks like cutting, drilling and polishing in many field of production.
2. In the middle of the century technological development reached the point to provide necessary condition to produce laboratory cultivated diamonds more popular as ”synthetic diamonds”. Synthetic diamonds were the answer to the need of high quality stones on lower prices.
As it was already mentioned nowadays diamonds are used mostly as tools and very few of them are actually jewelry. Because of its hardness and its toughness diamond handles almost all other natural and synthetic materials – metal, stone, ceramics, plastics, wood and etc. Therefore is it the patron of “Superabrasives” group. See more about another member of the Group: Borazon, Cubic Zirkonia/Feanit.
For the purpose diamonds become a part of the various tools, depending on the work they perform. Larger and specially shaped stones cut and drill, while smaller are designed as a part of a diverse family of mineral abrasives.
Synthetic detonation nanodiamonds are the most common material used for diamond abrasive products – powders, pastes, discs, belts and etc. Their small and almost identical grains form unified mass of high quality “diamond powder”.
In general Diamond abrasives are tools used for:
• imparting into desired shape
• smoothing of various materials and products.
The size of the grits varies and determines coarseness of Diamond abrasive powders. The bigger are the individual grains the stronger is the friction and more material is removed in the process. Therefore there are 3 main types of polishing Grits:
To illustrate their function we may give the following example of their usage:
Coarse is for shaping, medium is smoothing and the fine is giving the high luster of the workpiece.
Diamond abrasives as tools may be used for manual or machine work. There are several types of products that are included in the Diamond abrasives tools line. These instruments are designed for different type of wok and different technique of usage but have common characteristics by groups.
Bonded diamond abrasives
These are products that form one matrix. These tools’ bonding material is usually resin, clay or rubber powder.

Coated diamond abrasives:
Most of the diamond abrasives are fixed to some base/back. Commonly used for the purpose are materials like paper, cloth, rubber, resin, polyester or even metal. Typical abrasive of this type is Sandpaper.

Diamond paste is compound made of finest diamond pieces plus some kind of liquid. The color usually indicates the grit of the powder used. It is one of the best methods to polish sensitive and hard surfaces as metal blades, for example.
