Kukula Kwa Diamondi Lab
Carat ndi gawo la kulemera kwa diamondi.Carat nthawi zambiri imasokonezeka ndi kukula ngakhale kuti kwenikweni ndi kulemera kwake.Carat imodzi ikufanana ndi 200 milligrams kapena 0.2 magalamu.Sikelo ili m'munsiyi ikuwonetsa mgwirizano wa kukula pakati pa diamondi pakuwonjezera kulemera kwa carat.Kumbukirani kuti ngakhale miyeso yomwe ili pansipa ndi yofanana, diamondi iliyonse ndi yapadera.
Ma diamondi opangidwa ndi labu amatsata dongosolo lomwelo la 4Cs (kudula, mtundu, kumveka bwino ndi kulemera kwa carat) ngati diamondi zachilengedwe.M'munsimu muli chithunzithunzi chachidule cha gulu lirilonse: 1. Dulani: Kutanthawuza kulondola ndi khalidwe la diamondi yodulidwa, kuphatikizapo kufanana kwake, symmetry ndi polish.Daimondi yodulidwa bwino imasonyeza kuwala kokongola, ndikuwonjezera kukongola kwake.2. Utoto: Amatanthauza machulukidwe a mtundu wa diamondi, womwe ungakhale wosiyana ndi mtundu mpaka wachikasu, bulauni, ngakhale pinki, buluu, kapena wobiriwira.Mtundu wa diamondi ukakhala wotsika, umakhala wofunika kwambiri.3. Kumveka bwino: Kumatanthauza kukhalapo kapena kusakhalapo kwa zinthu zachilengedwe kapena zilema mkati mwa diamondi.Ma diamondi omveka bwino amakhala ndi zophatikizika pang'ono ndipo motero amaonedwa kuti ndi ofunika kwambiri.4. Carat kulemera: kumatanthauza kulemera kwa diamondi, 1 carat ndi yofanana ndi 0,2 magalamu.Kulemera kwa carat kumapangitsa kuti diamondi ikhale yamtengo wapatali.Komabe, ziyenera kudziwidwa kuti ma diamondi opangidwa ndi labu akhoza kukhala ndi zinthu zosiyana pang'ono ndi kufufuza zinthu poyerekeza ndi diamondi zachilengedwe, zomwe zingakhudze momwe amasiyidwira.Bungwe la International Gemological Institute (IGI) ndi Gemological Institute of America (GIA) limaperekanso malipoti a diamondi omwe amamera labu.
Mtundu Wa Daimondi Wa Lab: DEF
Mtundu ndi mtundu wachilengedwe womwe umawonekera mu diamondi ndipo susintha pakapita nthawi.Ma diamondi opanda mtundu amalola kuwala kochuluka kudutsa kuposa diamondi yamitundu, kutulutsa kuwala ndi moto.Pochita ngati prism, diamondi imagawa kuwala m'mitundu yosiyanasiyana ndipo imawonetsa kuwalako monga kuwala kokongola kotchedwa moto.
Labu Yakula Daimondi Kumveka: VVS-VS
Kumveka bwino kwa diamondi kumatanthauza kukhalapo kwa zonyansa pamwala ndi mkati mwake.Mwala ukachotsedwa pansi pa kaboni pansi pa dziko lapansi, tinthu ting'onoting'ono ta zinthu zachilengedwe timatsekeredwa mkati ndipo timatchedwa inclusions.
Kudula Kwa Daimondi Lab: EXCELLENT
Kudulidwaku kumatanthauza ngodya ndi kuchuluka kwa diamondi.Kudulidwa kwa diamondi - mawonekedwe ake ndi mapeto, kuya kwake ndi m'lifupi, kufanana kwa mbali - kumatsimikizira kukongola kwake.Luso limene diamondi imadulidwa nalo limasonyeza mmene imawalira komanso mmene imawalira.
