1991-2-1 · The growth process and morphological variations of diamond single crystals obtained by microwave plasma CVD of the CO-H 2 reactant system were observed using scanning electron microscopy. The optimum conditions for spontaneous nucleation and growth of diamond on a (100) Si wafer were microwave power of 550 W, total pressure of 30–60 Torr, total flow rate of 200 ml/min and .

As the growth in CVD method can not make the size of diamond larger, size of seed dominate the final diamond gem stone weight. The largest seed from EDP is 10x10mm and this can fabricate 3 crat or larger loose. You can select the size of seed from 5x5mm to 10x10mm. The regular thickness of seed is 0.3 or 0.2mm but you may require the thickness.
