Static-pressure strength, toughness index (IT) and thermal-toughness index (ITT) of each sample were analyzed on the basis of the experimental studies on the magnetic separation of diamond single crystal. The results show that the magnetism of synthetic diamond single crystal has an obvious influence on the mechanical performance. With the increase of magnetism, synthetic diamond single crystal becomes darker and darker in appearance color, and have more bubbles, impurities and defects inside the particles. Furthermore, their surface fineness observed under the microscope becomes worse. Meanwhile, the static-pressure strength, the IT under the normal temperature and ITT become lower and lower. The influence of magnetism on the static-pressure strength and the IT is slight, however, the influence on ITT is serious.
