Umbala weDayimane
Umbala wedayimani uhlelwe kwindawo yokujonga esemgangathweni.Iingcali zeGemologists zihlalutya umbala kuluhlu lwemibala ye-D ukuya ku-Z kunye nedayimane ebekwe phezulu, ijongwe ngecala, ukuququzelela umbono ongathathi hlangothi.
Diamond Ngokucacileyo
Ukucaciswa kwamabanga ngokwemigangatho eyamkelekileyo kumazwe ngamazwe kwi-10X yokukhulisa, ngokuhambelana nokubonakala, ubungakanani, inani, indawo kunye nohlobo lweempawu zangaphakathi kunye nomphezulu kweso sandiso.
Idayimani Cut
Iingcali zeGemologists ngokubanzi, imilinganiselo kunye ne-facet angles zithelekiswa nophononongo lokuqaqamba, umlilo, ukukhazimla kunye nepateni ukumisela iBanga lokuSika.
Ikharati yedayimani
Inqanaba lokuqala kuhlelo lwedayimani bubunzima bedayimani.Ubunzima beCarat yiyunithi yobunzima obuqhelekileyo bamatye anqabileyo.Ukuhlelwa kwedayimani kukwiindawo ezimbini zedesimali ukuqinisekisa ukuchaneka.
Ishishini ledayimani elebhu likhule liye lathandwa ngakumbi kwiminyaka yakutshanje.
"Iidayimani ezikhule kwiLebhu zithandwa kakhulu," utshilo uJoe Yatooma, umnini weDash Diamonds eWest Bloomfield.
U-Yatooma uthe iidayimani ezikhuliswe ilebhu ziye zaba yinto yokwenyani kuba ngoku zithathwa njengeidayimani “zokwenene”.
“Isizathu sokuba samkele iidayimani ezikhule kwilabhoratri apha eDash Diamonds kungenxa yokuba iGemologist Institute of America ngoku iyayivuma ilabhoratri ekhuliswe idayimani kwaye ibakala,” utshilo uYatooma.
Kwiliso lenyama phantse akunakwenzeka ukuchaza umahluko phakathi kwedayimani ekhuliswe ilebhu kunye nedayimani yendalo, nangona kunjalo kukho umahluko obonakalayo kwixabiso.
UYatooma wathelekisa izacholo ezimbini ezinenani elifanayo ledayimani.Eyokuqala yayineedayimani ezikhule ngokwendalo kwaye eyesibini wayikhankanya yayinedayimani ezikhuliswe ilebhu.
“Oku kuxabisa i-12-grand, oku kubiza i-4,500 yeedola,” ucacise watsho uYatooma.
Iidayimani ezikhuliswe kwiLab zikwajongwa njengezona zilungele indalo esingqongileyo kuba imigodi encinci ibandakanyekayo kwaye zikwajongwa njengezoluntu ngakumbi.
Kungenxa yokuba iidayimani ezembiwa ngokwendalo zisoloko zibizwa ngokuba ziidayimani zegazi, okanye iidayimani zongquzulwano.
Nditsho nesigebenga esithengisa idayimani, iDebeers, ingene kwindawo ekhuliswe ilebhu ngomgca wayo omtsha obizwa ngokuba yi-Lightbox, ethetha ngedayimani ezenziwe ngesayensi.
Abanye abantu abadumileyo baye bakhankanya inkxaso yabo yeedayimani ezikhuliswe ilebhu, njengoLady Gaga, uPenelope Cruz kunye noMeghan Markle.
Kubekho iinkxalabo ngeedayimani ezikhuliswe elebhu kule minyaka yakutshanje.
“Itekhnoloji ibingahambelani namaxesha,” utshilo uYatooma.
I-Yatooma ibonise ukuba iindlela zangaphambili zokuvavanya idayimani yokwenyani azikwazanga ukwahlula phakathi kwendalo kunye nelebhu ekhulileyo.
“Yenza umsebenzi wayo kuba ilabhu ekhuliswe idayimani yidayimani,” ucacise watsho uYatooma.
Ngenxa yetekhnoloji ephelelwe lixesha, uYatooma uthe umzi-mveliso unyanzelekile ukuba wamkele iindlela zovavanyo eziphucukileyo.Ukuza kuthi ga ngoku, uthe, kukho izixhobo ezimbalwa kuphela ezinokubona umahluko.
“Kubavavanyi abatsha, yonke into eluhlaza okwesibhakabhaka namhlophe ithetha kwendalo kwaye ukuba ilebhu ikhulisiwe ingavela ibomvu,” ucacise watsho uYatooma.
Umgca osezantsi, ukuba ungathanda ukwazi ukuba loluphi uhlobo lwedayimane onalo, iingcali zeshishini zincoma ukuba ivavanywe.
