DEF Umbala CVD ilebhu ikhule idayimani ezithengiswayo
Ilebhu yeCVD ikhule idayimani Ubungakanani
Ikharati yiyunithi yobunzima bedayimani.I-Carat idla ngokubhidaniswa kunye nobukhulu nangona ngokwenene ingumlinganiselo wobunzima.I-carat eyi-1 ilingana ne-200 milligrams okanye i-0.2 grams.Isikali esingezantsi sibonakalisa ubungakanani bobudlelwane obuqhelekileyo phakathi kwedayimani ezikhulayo zobunzima becarat.Khumbula ukuba ngelixa imilinganiselo engezantsi iqhelekile, zonke iidayimani kwilebhu yeCVD ezikhuliswe zahlukile.
Umbala: DEF
Umbala ngumbala wendalo obonakalayo kwilebhu ye-CVD ekhuliswe idayimani kwaye ayitshintshi ngokuhamba kwexesha.Ilebhu yeCVD engenambala iidayimani ezikhulileyo zivumela ukukhanya okungakumbi ukuba kudlule kunedayimani enemibala, kukhulula ukukhazimla nomlilo.Isebenza njengeprism, idayimani yahlula ukukhanya kube yimibala eyahlukeneyo ize ibonakalise oku kukhanya njengokulenya okumibalabala okubizwa ngokuba ngumlilo.
Ukucaca: VVS-VS
Ukucaca kwedayimani kwilebhu ye-CVD kubhekiselele kubukho bokungcola ngaphakathi nangaphakathi kwelitye.Xa ilitye elirhabaxa litsalwa kubunzulu bekhabhoni phantsi komhlaba, izinto ezincinci zendalo zihlala zivaleleke ngaphakathi kwaye zibizwa ngokuba zii-inclusions.
Sika: EXCELLENT
Ukusikwa kubhekiselele kwii-engile kunye nomlinganiselo wedayimane.Ukusikwa kwedayimane - ifom kunye nokugqiba kwayo, ubunzulu kunye nobubanzi bayo, ukufana kweenkalo - kugqiba ubuhle bayo.Ubuchule bokusikwa kwedayimani bumisela indlela ebonakalisa kakuhle ngayo kwaye iyakufihla ukukhanya.
