From Adamas to Bort

The word diamond comes from the ancient Greek word "adamas" which means "unbreakable, that cannot be tamed". Since its discovery thousands of years ago, diamonds had already lived up to its name as they are considered to be one of the hardest known naturally occurring minerals in the world. The hardness quality of the diamond makes it also an important mineral in industrial applications in addition to its use in jewelry.

Diamond is a material renowned for its unparalleled physical qualities. Because of this, the only material that can scratch a diamond is another diamond. A polished diamond can last a long time and would not be scratched unless it is rubbed against another diamond. The best industrial-strength abrasives were made with diamond dust.

In the industry sector, diamonds of high dispersion index, extreme hardness, and extremely high thermal conductivity with a 900-2320 W/m K are most useful. These properties are the factors that make a diamond exceptionally worthy in industrial applications, it is an ideal material for grinding and cutting tools. Diamonds that are commonly used in industry are the less expensive ones. These include the flawed, the colored, and the unclear diamonds. These industrial-grade diamonds are commonly known as bort.
