3. Ukucaca
Amadayimane ahlukaniswa ngokucaca, okusho ukuthi idayimane lihlanzeke ngokoqobo.Ukuhlanzeka kwedayimane kungabonwa ngaphansi kwesibonakhulu esiphindwe kashumi, futhi lapho kusobala kakhulu amaphutha, imihuzuko, njll., kwehla inani, futhi ngokuphambene nalokho.Ngokusho kokucaca kwamadayimane amakhulu ahlukaniswe abe yizinhlobo eziyisi-6, ngokulandelana FL, IF, VVS, VS, S, I.
4. Sika
Hlukanisa idayimane kokusikiwe, lapho okusikiwe kube ngcono, yilapho idayimane likwazi ukubonakalisa ukukhanya ukuze lifinyelele isilinganiso esifanele.Izimo ezivame kakhulu zokusika idayimane yinhliziyo, isikwele, okusaqanda, okuyindilinga nomcamelo.Kulokhu, amadayimane ahlukaniswe abe izinhlobo ezinhlanu: EX, VG, G, FAIR kanye POOR.
