ILab eKhulisiweyo yeDayimane Ubungakanani
Ikharati yiyunithi yobunzima bedayimani.I-Carat idla ngokubhidaniswa kunye nobukhulu nangona ngokwenene ingumlinganiselo wobunzima.Ikharati enye ilingana ne 200 milligrams okanye 0.2 grams.Isikali esingezantsi sibonakalisa ubungakanani bobudlelwane obuqhelekileyo phakathi kwedayimani ezikhulayo zobunzima becarat.Khumbula ukuba ngelixa imilinganiselo engezantsi iqhelekileyo, yonke idayimani yodwa.
Iidayimani ezikhuliswe kwiLebhu zilandela ii-4Cs ezifanayo (ukusikwa, umbala, ukucaca kunye nobunzima be-carat) inkqubo yokuhlela njengedayimani zendalo.Ngezantsi sisishwankathelo esifutshane sodidi ngalunye: 1. Sika: Ibhekisa ekuchanekeni kunye nomgangatho wokusikwa kwedayimani, kubandakanywa ubungakanani bayo, i-symmetry kunye nepolishe.Idayimani esikwe kakuhle ibonakalisa ukukhanya kakuhle, yongeza ukuqaqamba kwayo.2. Umbala: Ubhekisela ekuzalisekeni kombala wedayimani, onokususela ekubeni ungenambala ukuya kutsho kumthubi, omdaka, okanye opinki, ozuba, okanye oluhlaza.Xa idayimani inombala omncinci, ixabiseke ngakumbi.3. Ukucaca: Kubhekiselele kubukho okanye ukungabikho kwayo nayiphi na indibaniselwano yendalo okanye amabala ngaphakathi kwedayimani.Iidayimani ezicacileyo eziphezulu zinee-inclusions ezimbalwa kwaye ngoko ke zibhekwa njengexabiso.4. Ubunzima beCarat: bubhekisela kubunzima bedayimani, i-carat eyi-1 ilingana ne-0.2 grams.Okukhona ubunzima becarat, kokukhona ixabiso ledayimani.Nangona kunjalo, kufuneka kuqatshelwe ukuba iidayimani ezikhule kwilebhu zinokuba neempawu ezahlukileyo kwaye zilandelele izinto xa zithelekiswa nedayimani zendalo, ezinokuchaphazela indlela ezihlelwa ngayo.I-International Gemological Institute (IGI) kunye neGemological Institute of America (GIA) nazo zibonelela ngeengxelo zokuhlelwa kweedayimani ezikhuliswe elebhu.
ILab Ekhule Umbala weDayimane: DEF
Umbala ngumbala wendalo obonakalayo kwidayimani kwaye awutshintshi ngokuhamba kwexesha.Iidayimani ezingenambala zivumela ukukhanya okungakumbi ukuba kudlule kunedayimani enemibala, kukhulula ukubengezela nomlilo.Isebenza njengeprism, idayimani yahlula ukukhanya kube yimibala eyahlukeneyo ize ibonakalise oku kukhanya njengokulenya okumibalabala okubizwa ngokuba ngumlilo.
ILebhu eKhulisiweyo yeDayimani Ukucaca: VVS-VS
Ukucaca kwedayimani 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.
ILebhu eKhulisiweyo yeDayimani Cut: 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.
