Umehluko phakathi kwedayimane lemvelo kanye nelebhu elikhuliswe yidayimane usukela endleleni enziwe ngayo.Amadayimane akhule elebhu enziwa umuntu elebhu kuyilapho amadayimane emvelo edalwa emhlabeni.
Amadayimane okuqala okwenziwa ayimpumelelo enziwa ngokulingisa imvelo ngokukhiqiza i-High Pressure/High Temperature (HPHT).Kunezinqubo ezintathu zokukhiqiza eziyisisekelo ezisetshenziselwa ukwenza amadayimane e-HPHT: umshini wokunyathelisa webhande, umshini wokunyathelisa we-cubic, kanye nomshini wokunyathelisa we-split-sphere (BARS).Umgomo wenqubo ngayinye ukudala indawo yokucindezela okuphezulu kakhulu kanye nezinga lokushisa lapho ukukhula kwedayimane kungenzeka khona.Inqubo ngayinye iqala ngembewu yedayimane encane efakwa kukhabhoni bese ifakwa ngaphansi kwengcindezi ephakeme kakhulu kanye nezinga lokushisa ukuze kukhule idayimane.
Enye indlela edumile yokukhulisa idayimane lokwenziwa i-chemical vapor deposition (CVD).Ukukhula kwenzeka ngaphansi kwengcindezi ephansi (ngaphansi kwengcindezi yasemkhathini).Kuhilela ukuphakela ingxube yamagesi (ngokuvamile i-methane engu-1 kuye ku-99 kuya ku-hydrogen) ibe yi-chamver futhi ihlukaniselwe kuma-radicals asebenza ngamakhemikhali ku-plasma ebaswe ama-microwave, i- hot filament, i-arcdischarge, ithoshi yokushisela noma i-laser.Le ndlela isetshenziselwa kakhulu ukugqoka, kodwa futhi ingakhiqiza ikristalu eyodwa ngamamilimitha ambalwa ngosayizi.
