Special discount for this low quality cvd rough diamond.
Size: 8*8 9*9 10*10 11*11 12*12 13*13
Thickness:1-2mm
Quality: Rough. both side unpolished.
With small polycrystalline spot,and small crack on the side.
In hands for 2000CT. as picture .
It is very good for industry tools.
CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
