4C Mulingo wa diamondi wakula labu
Mtundu
Mtundu wa dayamondi wakula labu umayikidwa m'malo owoneka bwino.Akatswiri a miyala amasanthula mtundu wamtundu wa D mpaka Z ndi diamondi yoyikidwa mozondoka, kuwonedwa m'mbali, kuti azitha kuwona m'mbali.
Kumveka bwino
Makalasi momveka bwino molingana ndi miyezo yovomerezeka padziko lonse lapansi pakukula kwa 10X, kutengera mawonekedwe, kukula, nambala, malo ndi mawonekedwe amkati ndi pamwamba pakukula kumeneko.
Dulani
Akatswiri a miyala yamtengo wapatali, miyeso ndi makona a nkhope amafaniziridwa ndi maphunziro a kuwala, moto, scintillation ndi pateni kuti adziwe Gawo la Dulani.
Carat kulemera
Gawo loyamba pakugawira ma diamondi omwe amakula labu ndikulemera kwa diamondi.Kulemera kwa Carat ndi gawo lolemera la miyala yamtengo wapatali.Kuyika kwa diamondi ndi malo awiri a decimal kuti atsimikizire zolondola.
