The industrial diamonds are made from the same substance as gem-grade diamond, namely crystals of the elemental carbon, but we describe the same mineral differently under different condition. How to classify diamonds?
According to name, the industrial diamonds are mostly used in mineralogy, but the gem-grade diamonds are mostly used in gemology. That is to say, the industrial diamonds are used to describe the crystals of the elemental carbon, and the gem-grade diamonds are used to describe jewelry that has been cut and polished. Specifically, industrial diamond is raw material, but the gem grade diamonds is the product after the industrial diamond has been processed.
According to the application, the diamond can be divided into industrial diamond and gem-grade diamond.
The features of gem-grade diamond: the crystal of it is relatively perfect, with high transparency; it tends to colorless or light yellow in color, little impurity, less cracks or almost no. After cutting and processing, it becomes a gem grade diamond, which is used for the setting and sale of diamond ornaments.
The features of industrial diamonds: poor color, poor crystal quality, and a lot of defects in it, so it can not be used as gem grade diamond. The industrial diamonds are widely used in industrial tools and equipments such as cutting tools, drills, grinding, saw blades, hardness, optical instrument and wheel dresser.
