The diamond single crystals have smooth, transparent surfaces and other characteristics identical to that of high-pressure, high-temperature synthetic diamond. In addition, the crystals can be produced at growth rates from 50 to 150 μm/h, which is up to 2 orders of magnitude higher than standard processes for making polycrystalline MPCVD diamond.

Synthetic diamond - Wikipedia

Synthetic diamond (also referred to as laboratory-grown diamond, laboratory-created diamond, or cultured diamond) is a diamond made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form.. Synthetic diamond are different from natural diamond created by geological processes and imitation diamond made of non-diamond material.

These parameters are far beyond growth conditions for HF-CVD diamond coating processes. Extremely low methane content in the feed gas along with high substrate temperatures allows single diamond nuclei of a certain minimum size to grow stable. Crystals up to 100 μm in diameter were successfully synthesized on ultrasonic pretreated substrates.
