Ukuba ucinga ngokutyala imali kwindandatho yokubandakanya, kuyahlawula ukuqonda isilinganiselo sokucaca kwedayimane. Ubungakanani kunye nenani leziphene kwidayimane linempembelelo enkulu kwixabiso lelitye.
Yintoni Ukucaca?
Uninzi lwedayimane lwenziwa ngaphezulu kwesigidi seminyaka eyadlulayo, xa iiminerali ezinekhabhoni nzulu eMhlabeni zaphendula kuxinzelelo olukhulu noluzinzileyo. Iziganeko zenyikima zizisa ezi dayimani emhlabeni, apho zimbiwa khona, zisikwe, zize zenziwe ubucwebe.

- Imifanekiso yeeRandi zeDayimani yokuzibandakanya
Uninzi lwedayimane lwenziwe ngokwamanqanaba, sesona sizathu siphambili sokuba neziphene okanye inclusions. Ezi ziphene ziimali ezincinci zezinto ezingezizo zedayimane ngaphakathi kwelitye. 'Ukucaca kwedayimane' kubhekisa kwiinkqubo zokulinganisa ezisetyenziselwa ukuchaza ezi mpazamo.
Ukuqonda isikali sokucaca kweGIA ye-GIA
Abaphandi ngeGemological Institute of America (GIA) bayila Ukucaciswa kokucaciswa kwedayimane ngo-1953. Ngexesha le-1970s, amalungu e-GIA aqaphela ukuba ukusika iidayimani kuye kwaba krwada ukuphendula isikali, ke bayihlaziya ukuze ibandakanye ukuhlelwa kweedayimani ezingalunganga.

Inkqubo yokuhlela iidayimani ifuna iminyaka yoqeqesho kunye nezixhobo ezizodwa ezikhanyisa nezenza nkulu idayimani. I-GIA diamond graders zisebenzisa iinkqubo ezimiselweyo zokuhlola kwaye jonga ikota yesine yelitye elineentsilelo.
Ukucaciswa kokucaciswa kusekwe kwindlela ekulula ngayo okanye ekunzima ngayo kubathengisi bezinto ezithengisa iimpahla ukuba babone iziphene kwidayimane. Ezinye iziphene zinokubonakala ngeliso lenyama, zinika idayimani inqanaba lokucaca elisezantsi. Ezinye iziphene zinokubonwa kuphela kukhuliso, kwaye ezo dayimani zifumana inqanaba eliphezulu. Iidayimani ezimbalwa azinazimpazamo kwaphela.
Zininzi izinto ezinokuba nefuthe kwinqanaba lokucaca ledayimane:
- Inani lokufakwa kwilitye
- Ubungakanani bokufakwa nganye
- Uhlobo lokubandakanywa kunye nendlela ekubuchaphazela ngayo ubuqaqawuli bedayimane kunye nokuthembeka kolwakhiwo
- Ukubekwa kokufakwa
- Inani lokwahluka phakathi kokubandakanywa kunye nedayimane ejikelezileyo
Iidayimani ezingenasiphako ngaphakathi nangaphakathi
Ukucaciswa kokucaciswa kwe-GIA kwezona dayimani zigqibeleleyo zezi zilandelayo:
- I-FL : Iidayimani ezingenasiphako azinasiphako kumphezulu kwaye akukho zibandakanyiweyo zibonakalayo ekukhuliseni kwe-10x. Kunqabile kakhulu ukufumana iidayimani zalo mgangatho kwindalo, nangona umlinganiso ongenasiphako uqhelekile kumatye enziwe elebhu.
- UKUBA : Eli banga, elalifakwe ngoo-1970, lithetha ukuba idayimani ayinasiphako ngaphakathi kwi-10x magnification. Inokuba neziphene kumphezulu, kodwa zihlala zingabonakali ngamehlo. Ezi dayimani zinqabile kakhulu.
Kakhulu, kancinane kakhulu Iidayimani ezibandakanyiweyo
VVS1 kwaye VVS2 Iidayimani zinokufakwa okuncinci kakhulu. Kula matye, igrader yedayimani enobuchule ayizokwazi ukubona iziphene eziphantsi kwe10x. Ezi mpazamo azibonakali ngamehlo. Iidayimani ze-VVS2 zinokufakwa okuthe kratya kuneedayimani zeVVS1, kodwa zonke iidayimani ezikudidi lweVVS lokucacisa kwinqanaba zinokucaca okugqwesileyo.
Kancinci kakhulu ifakiwe iDayimane
Iidayimani ezibandakanyiweyo zincinci zibanjiwe njenge VS1 okanye VS2 . Kuzo zombini ezi meko, abaqeqeshi beedayimani abaqeqeshiweyo baya kubona kuphela iziphene ezincinci phantsi kokuphakanyiswa kwe-10x. Kwiidayimani ze-VS2, iziphene azifane zibonakale ngamehlo, nangona abo baqeqeshiweyo bedayimane banokwazi ukuzibona kwiimeko ezithile.
yintoni oza kuyinika kwitheko lothethathethwano
Kancinci iDayimane
Kwiidayimani ezifakwe kancinane, ezifumana amabakala SI1 okanye SI2 , abaqeqeshiweyo begrade baya kuba nakho ukubona iziphene phantsi kokuphakanyiswa kwe-10x. Ezi mpazamo zinokubonakala nakwiliso lenyama. Iidayimani ze-SI1 kunye ne-SI2 zixhaphake kakhulu kunamabanga aphezulu, zisenza ezi dayimani zibaluleke kancinci.
Iidayimani ezibandakanyiweyo
Inkqubo ye- I1 , I2 , kunye I3 amabakala ayongezwa ngee-1970. Ezi dayimani zinobungakanani obahlukeneyo bokufakwa, uninzi lwazo lubonakala ngamehlo. Ezinye iidayimani ze-I3 zinokuba nemicimbi ngokuzinza ngenxa yeempazamo zazo. Iidayimani ezibandakanyiweyo ziqaqambile kancinci kunamanye amabakala, kuba iziphene zinokuchaphazela ukukhanya kwidayimani.
Ezinye iiNkqubo zokuCwangciswa kweDayimane
I-GIA ayisiyiyo kuphela iziko elinikezela ngamabakala okucaciswa. Ukongeza kwinani leelebhu ezincinci kunye nemibutho yabucala, ezi arhente zilandelayo zikwabeka iidayimani ukucaca:
- Umbutho waseMelika wamaGem Enye yeenkqubo ezaziwayo eMelika emva kwe-GIA, isikali sokucaciswa kwe-AGS sisebenzisa imilinganiselo yamanani ukusuka ku-0-10.
- IZiko lezeMfundo yeZizwe ngezizwe : Inkqubo yokucacisa ngokucacileyo iyafana ne-GIA, kodwa inamabanga ali-10, aqala ngeNgaphakathi engenasiphako (IF).
- I-International Confederation of jewelry, i-Silverware, iDayimane kunye namatye : Lo mbutho usebenzisa inkqubo ebekwe ngokobunzima (ngaphezulu okanye ngaphantsi kwe-0.47 carats), kunye namabanga ukusuka kwiLoupe Clean ukuya kwiPiqué 3.
- IBhunga leDayimani laMazwe ngaMazwe I-IDC isebenzisa inkqubo ekufuphi ne-International Confederation of jewelry, Silverware, Diamonds and Stones, kodwa azihlukanisi iinkqubo zokuhlela ngokobunzima.
- Ilebhu yeLebhu yaseYurophu I-EGL inamabakala e-diamond angama-11 afana ne-GIA, kodwa yahlukile kumgangatho we-GIA kwinto leyo eqala ngaphakathi ingenasiphako kwaye inkqubo ibandakanya inqanaba le-SI3.
Ukuya kuthi ga kwinqanaba elithile, isikali esivela kule mibutho sihambelana nesikali se-GIA; Nangona kunjalo, kukho umahluko kwiileta nakumanani asetyenzisiweyo ukubonisa inqanaba lokucaca. Ukuba ijeeler yakho ikubonisa ilitye ngenye yezi ndlela zokulinganisa, mbuze ukuba achaze ukuba lithelekiswa njani nesilinganiselo sokucaca kwedayimani se-GIA.
Iimpazamo kuMgangatho okanye ngaphakathi
Zimbini iintlobo eziphambili zeziphene zedayimani, zombini ezinokuthi zibe negalelo ekucacisweni kwedayimani. Ngokwesiqhelo, i jewelers zibhekisa kwiimpazamo zomhlaba 'njengeziphako.' Oku kunokubandakanya imingxunya emincinci okanye imingxunya, ukukrwela, okanye iichips. Iimpazamo zangaphakathi zibizwa ngokuba yi 'inclusions' kwaye zinokubandakanya iindawo ezinamafu, iintsiba, imingxunya, kunye nedipozithi. Kukho umahluko omkhulu kubungakanani bezi ziphene kunye nendawo ezihlala kuyo phakathi kwelitye.
Ngubani owenza i-capricorn kunye
Abasiki bedayimani, abathi bafumane uqeqesho kunye nokuqeqeshelwa umsebenzi, kufuneka bathathe isigqibo ngendlela yokusika idayimani ukwandisa ubunzima becatwe ngeli lixa kuncitshiswa ezi mpazamo. Emva kokuba iidayimani zisikiwe zaza zapholiswa, babelwa ibakala elichaza ukucaca kwelitye.
Iziphene zokuzifihla
Iziphene nazo zinokufihlwa elebhu ukunqanda ukufunyanwa ngamehlo angenamava. Oku kucaca kuphuculwe iidayimani zinomtsalane ngakumbi ngelixa kugcinwa iindleko zizonke ezifikelelekayo. Iindlela zokuphucula ukucaca kwedayimani zibandakanya ukubhola kwelaser ukususa ukubandakanywa kunye nokwaphuka kokugcwalisa iintanda.
Uluhlu lwamazwe angama-50 kunye neentloko
Laser ukubhola
Ngaphandle kokuguqula amandla edayimani, ukubola kwelaser kususa ukubandakanywa okusisigxina. Kuba nzima kakhulu ukufumanisa xa iindawo ezibiweyo zelaser zizaliswe yinto ecacileyo. Nangona kunjalo ukuzaliswa akuhlali ngokusisigxina kwaye ilitye lichaphazeleka ngakumbi kukukhukuliseka kwemichiza kunye nomnye umonakalo.
Ukuzalisa ulwaphuluko
Olu nyango luzalisa iintanda ezincinci ngento ecacileyo, efana neglasi. Yenza ukukhohlisa okubonakalayo okufihla iintanda kubabukeli abaqhelekileyo. Ukuzaliswa kwesahlulo akuhlali ngokusisigxina, nangona kunjalo, kwaye nakuphi na ukucoca okanye ubushushu ekulungisweni okanye elangeni kunokususa okanye kubenze mnyama ubushushu, oko kutyhila ukwaphuka.
Impembelelo yokuCaca kwiXabiso
Ukucaca kwedayimane yinto enkulu ekumiseleni indleko zelitye. Isiphene esibonakalayo sinokuphazamisa idayimani efanelekileyo, lihlise ixabiso kakhulu. Uninzi lwabantu luthanda amatye angenasiphako, kwaye unyango lwelebhu lunokunceda ukwandisa ukucaca kwedayimane ngelixa ligcina ixabiso elifikelelekayo kumakhonkco okuzibandakanya kunye nezinye iintlobo zobucwebe. Amatye ahlala ekhululekile ngokwasendalweni-okanye anezinto ezincinci, ezingafumanekiyo-zithwala awona maxabiso aphezulu.
