Ukuze bathenge ubucwebe bedayimane obufiselekayo, abathengi badinga ukuqonda amadayimane ngombono wochwepheshe. Indlela yokwenza lokhu ukuqaphela i-4C, izinga lamazwe ngamazwe lokuhlola amadayimane. Ama-C amane yi-Weight, i-Colour Grade, i-Clarity Grade, ne-Cut Grade.
1. Isisindo se-Carat
Isisindo sedayimane sibalwa kuma-carat, noma ngokuvamile abizwa ngokuthi "amakhadi", i-carat engu-1 ilingana namaphuzu angu-100, idayimane elingu-0.5 carat, lingabhalwa njengamaphuzu angu-50. Ikhalori eyodwa ilingana namagremu angu-0.2, okusho ukuthi igremu elilodwa lilingana namakholori angu-5. Uma idayimane likhulu, kufanele libe yivelakancane. Kubathengi bedayimane abaqala ngqa, zama ukuqala ngokukhetha usayizi wedayimane. Kodwa-ke, ngisho namadayimane amabili esisindo esifanayo se-carat angahluka ngenani ngenxa yemibala ehlukene, ukucaca nokusikwa, ngakho-ke kunezinye izici okufanele zicatshangelwe lapho kuthengwa amadayimane.
2. Ibanga Lemibala
Okuvame kakhulu emakethe amadayimane ochungechunge lwaseKapa, angahlukaniswa ngokuthi "angenambala obala" kuya "cishe angenambala" kanye "nophuzi okhanyayo". Ibanga lombala linqunywa ngokwezinga le-GB/T 16554-2017 “Ibanga Ledayimane”, kusukela kumbala othi “D” kuye kokuthi “Z”. Umbala u-D, E, F, owaziwa nangokuthi ongenambala obala, uyivelakancane kakhulu, umehluko phakathi kwawo ukuncika kochwepheshe ngokucophelela ukuze bakhombe. Umbala ovame kakhulu u-G kuya ku-L, owaziwa nangokuthi cishe awunambala. Ochwepheshe kuyoba lula ukuhlukanisa, kodwa umuntu ovamile kunzima ukuhlukanisa, uma kubekwe ubucwebe kunzima kakhulu ukukubona. Umbala ungaphansi kuka-M, owaziwa nangokuthi ophuzi okhanyayo, umuntu ovamile angase akwazi ukuhlukanisa, kodwa intengo ngokusobala ishibhile kakhulu. Eqinisweni, amadayimane aneminye imibala, ebizwa ngokuthi amadayimane anemibala, ingaba phuzi, pink, blue, green, red, black, kaleidoscope, kodwa engavamile kakhulu, inani eliphakeme kakhulu.
3. Ukucaca
Idayimane ngalinye lihlukile futhi liqukethe okufakiwe, njengophawu lokuzalwa lwemvelo, futhi inombolo, usayizi, umumo nombala walokhu kuhlanganiswa kunquma ukucaca nokuhluka kwedayimane. Eqinisweni, ukufakwa kwedayimane okuningi akubonakali ngeso lenyama. Uma kuncipha ukufakwa kwedayimane, kulapho ukukhanya kuphindeka khona, futhi idayimane likhanya kabili. Ngokwezinga laseChina “lokugreda kwedayimane”, ukucaca kokuhlonza kufanele kwenziwe ngaphansi kokukhulisa izikhathi eziyi-10, futhi amamaki akho ami kanje:
I-LC empeleni ayinasici
Izici zangaphakathi nezangaphandle ezincane kakhulu ze-VVS (ochwepheshe kufanele babheke ngokucophelela ukuze bazithole)
I-VS Elula izici zangaphakathi nezangaphandle (okunzima ukuthola ochwepheshe)
Izici ze-SI ezincane zangaphakathi nezangaphandle (kulula ngochwepheshe ukuthi bathole)
I-P inezici zangaphakathi nezangaphandle (ezibonakala ngeso lenyama)
Amadayimane angaphezu kwe-VVS awavamile. Okuqukethwe kwe-VS noma i-SI nakho akubonakali ngeso lenyama, kodwa intengo ishibhile, futhi abantu abaningi bayathenga. Ngokuqondene ne-P-class, intengo iphansi kakhulu, futhi uma ikhanya ngokwanele futhi ikhanya ngokwanele, ingabuye ithengwe.
Okwesine, Sika
Ukusika kumelela izinto eziningi, ngaphezu kokuma, kufaka phakathi i-Angle, isilinganiso, ukulinganisa, ukugaya nokunye. Lapho isilinganiso sokusika idayimane sifaneleka, ukukhanya kufana nokuvezwa kwesibuko, ngemva kokuphikiswa kwezingxenye ezihlukene, okufingqiwe phezulu kwedayimane, kukhiphe ukucwazimula okukhazimulayo. Idayimane elisikiwe lijule kakhulu noma lingashoni kakhulu lizokwenza ukukhanya kugeleze kusuka phansi futhi kulahlekelwe ukucwebezela kwakho. Ngakho-ke, amadayimane asikwe kahle ngokwemvelo anenani eliphakeme.
