Yellow, White, Blue HPHT Mono Diamond Square Substrate CVD Diamond Seeds
Single crystal CVD uses a single crystal diamond substrate as a base to grow single crystal diamond by vapor phase epitaxy.
The single crystal diamond substrate used can be natural diamond, HPHT diamond or CVD diamond, HPHT diamond has lower stress
distribution than CVD diamond, easier available than natural diamond, is a good diamond seeds for growing CVD diamond.
