For the natural diamond pull the peak spectrum, has the following characteristics:
(1) 1332 shows the presence of diamond at the front of the blade.
(2) The waveform amplitude (FWHM) is 4.1 cm-1
Show as pure diamond. ND is the hardest known mineral in the present, mainly for the preparation of tool turning tools. Natural diamond tool fine grinding edge radius of up to 0.01 ~ 0.002 & micro; m. One of the natural single crystal diamond (Single Crystalline Diamond, SCD) tool cutting edge parts by high magnification 1500 times still observed blade smooth. SCD turning aluminum piston when the Ra can reach 4 & m; and in the same cutting conditions with PCD tool processing surface rough when the Ra is 15 ~ 50 m; m. So use SCD tool with precision lathe for precision and ultra-precision machining, access to mirror surface.
