The quality of a diamond fluctuates from the finest pure crystal to the most low-graded crystals. Cracks, impurities, and flaws can be considered as factors that can degrade the quality of a diamond. The most well-known diamond dressers are Single Point Dressers and Profile Dressers that are utilized for huge grinding wheels, blade-shaped dressers and hand dressers.

On the other hand, profile dressers applied for straight and profile dressing. Other common dressers available in the market are multi-point/impregnated dressers, chisel and cone profile tools, and PCD form dressers which applied to meet customized requirements.
