DEF Mtundu CVD labu wokulirapo diamondi akugulitsidwa
CVD lab kukula diamondi Kukula
Carat ndi gawo la kulemera kwa diamondi.Carat nthawi zambiri imasokonezeka ndi kukula ngakhale kuti kwenikweni ndi kulemera kwake.1 carat 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 yofananira, ma diamondi aliwonse a CVD omwe amakula ndi apadera.
Mtundu: DEF
Utoto ndi mtundu wachilengedwe womwe umawonekera mu labu ya CVD yokulirapo diamondi ndipo susintha pakapita nthawi.Ma diamondi okulirapo opanda utoto a CVD amalola kuwala kochulukirapo kuposa diamondi yamitundu, kutulutsa kuwala ndi moto.Pochita ngati prism, diamondi imagawa kuwala m'mitundu yosiyanasiyana ndipo imawonetsa kuwalako monga kuwala kokongola kotchedwa moto.
Kufotokozera: VVS-VS
Kumveka bwino kwa diamondi ya CVD kumatanthawuza kukhalapo kwa zonyansa mkati ndi mkati mwa mwala.Mwala ukachotsedwa pansi pa kaboni pansi pa dziko lapansi, tinthu ting'onoting'ono ta zinthu zachilengedwe timatsekeredwa mkati ndipo timatchedwa inclusions.
Dulani: 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.
