Izinhlobo zamadayimane udinga ukwazi ngaphambi kokuthenga idayimane

Amadayimane ahlala ethandwa ngabantu abaningi, abantu bavame ukuthenga amadayimane njengezipho zamaholide bona noma abanye, kanye neziphakamiso zomshado, njll.

Okokuqala, ngokusho kokwakheka kwesigaba

1. Amadayimane anemvelo asungule
Amadayimane abiza kakhulu emakethe ngokuvamile akhiwa yi-crystallization ngokuhamba kwesikhathi endaweni yokushisa ephezulu kanye nengcindezi (imvamisa ukuntuleka komoya-mpilo), futhi amadayimane amadala atholakele angaba yizigidi eziyizinkulungwane ezi-4,5 ubudala. Lolu hlobo lwedayimane luphezulu ngenani ngoba aluvamile.

2. Amadayimane okufakelwa
Ngokuthuthukiswa kwesayensi nobuchwepheshe, kunamadayimane amaningi okufakelwa emakethe, futhi abantu abaningi bangenza amadayimane okulingisa ngengilazi, spine, zircon, strontium titanate nezinye izinto ezinjalo, futhi inani lamadayimane anjalo lihlala liphansi. Kepha kufanelekile ukuqaphela ukuthi amanye ala madayimane okwenziwa abukeka kangcono kakhulu kunamadayimane anokwemvelo.

Okwesibili, ngokusho kweDayimane 4C Ibanga

1. Isisindo
Ngokwesisindo sedayimane, isisindo esikhulu sedayimane, idayimane elibaluleke kakhulu. Iyunithi elalisetshenziselwa ukukala isisindo sedayimane yi-carat (CT), ne-carat eyodwa ilingana namagremu amabili. Esivame ukubizela ngamaphuzu ayi-10 namaphuzu angama-30 ukuthi i-carat eyi-1 ihlukaniswe izingxenye eziyi-100, ngalinye liyiphuzu elilodwa, okungukuthi, amaphuzu ayi-10 amakharati angu-0,3.

2. Umbala
Amadayimane ahlukaniswe ngombala, okusho ukujula kombala kunokuba uhlobo lombala olungezansi. Ngokuya ngokujula kombala wedayimane ukuthola uhlobo lwedayimane, ukuvalwa kwedayimane kungenamibala, kuhlangana ngokwengeziwe. Kusuka ku-D grade diamonds kuya ku-Z Grade Diamonds kuya kuba mnyama futhi kumnyama, i-DF ayinamibala, i-GJ icishe ibe nombala, futhi amadayimane we-K-grade acishe alahlekelwe yinani elihlanganayo.

3. Ukucaca
Amadayimane ahlukaniswe ukucaca, okuyinto ehlanzekile ngayo idayimane. Ubumsulwa bedayimane bungabonakala ngaphansi kwesimo semicroscope esinamashumi ayisikhombisa, futhi okusobala okusobala noma okusobala amaphutha, ukuklwebheka, njll. Ngokokucaciswa kwamadayimane amakhulu ahlukaniswe ngezinhlobo ezi-6, ngokulandelana, uma, ama-vv, vs, s, i.

4. Sika
Hlukanisa idayimane kusuka kokusikiwe, okungcono ukusikwa, lapho idayimane lingakhombisa ukukhanya kokuthola isilinganiso esifanele. Amajamo ajwayelekile wedayimane amajamo ayinhliziyo, isikwele, i-oval, nxazonke kanye nomcamelo. Kulokhu, amadayimane ahlukaniswe ngezinhlobo ezinhlanu: Ex, VG, G, Fair and Great.

Okwesithathu, ngokusho kwesigaba sombala wedayimane

1, idayimane elingenamibala
Amadayimane angenamibala abhekisela kuhlobo olungenamibala, acishe abe nombala noma olwenziwe ngamadayimane aphuzi aphuzi, futhi ukuhlukaniswa kwamadayimane angenamibala kukhulunywa ngenhla ngokuhambisana nokujula kombala ukuze uhlukanise.

2. Amadayimane anemibala
Isizathu sokwakheka kwamadayimane anemibala ukuthi izinguquko ezicashile ngaphakathi kwedayimane liholela kumbala wedayimane, futhi ngokuya ngombala ohlukile wedayimane, idayimane lihlukaniswe ngezinhlobo ezinhlanu. Ngokuya ngentengo, ihlukaniswe ngamadayimane abomvu, amadayimane aluhlaza okwesibhakabhaka, amadayimane aluhlaza, amadayimane aphuzi namadayimane amnyama (ngaphandle kwamadayimane amnyama).
