Diamond is known for its unique hardness. Strong and tough carbon compounds formed billions of tetrahedral cells which are the source of mechanical strength of diamonds. Perfect, clean diamonds of (111) and (100) have the highest level of rigidity and hardness and are ideal for high-precision mechanical engineering applications.

The ideal crystal purity guarantees high wear resistance and low coefficient of tool friction even if a diamond layer is very thin. Strong diamond material significantly increases life-time of an instrument and equipment, providing more cost-effective solution in long-term perspective.
