Kodi tiyenera kuyang'ana chiyani tisanagule diamondi?Zigawo zingapo zomwe muyenera kuzidziwa musanagule diamondi

Kuti agule zodzikongoletsera za diamondi zofunika, ogula ayenera kumvetsetsa diamondi kuchokera kumalingaliro a akatswiri. Njira yochitira izi ndikuzindikira 4C, muyezo wapadziko lonse wowunika diamondi. Ma C anayi ndi Weight, Colour Grade, Clarity Grade, ndi Cut Grade.

1. Kulemera kwa Carat

Kulemera kwa diamondi kumawerengedwa mu carats, kapena kutchedwa "makadi", 1 carat ndi yofanana ndi mfundo 100, diamondi ya 0,5 carat, ikhoza kulembedwa ngati mfundo 50. Kalori imodzi ndi yofanana ndi magalamu 0,2, kutanthauza kuti gramu imodzi ndi yofanana ndi ma calories 5. Kukula kwa diamondi, kuyenera kukhala kosowa. Kwa ogula diamondi nthawi yoyamba, yesani kuyamba ndi kusankha kukula kwa diamondi. Komabe, ngakhale diamondi ziwiri zolemera za carat zimatha kusiyana mtengo chifukwa cha mitundu yosiyanasiyana, kumveka bwino ndi kudula, kotero pali mbali zina zomwe ziyenera kuganiziridwa pogula diamondi.

2. Gulu la Mitundu

Zomwe zimapezeka pamsika ndi diamondi zamtundu wa Cape, zomwe zitha kutchulidwa kuti "zosawoneka bwino" mpaka "zopanda mtundu" komanso "zachikasu chowala". Mtundu wa utoto umatsimikiziridwa molingana ndi muyezo wa GB/T 16554-2017 "Diamond Grading", kuyambira "D" mtundu mpaka "Z". Mtundu ndi D, E, F, wotchedwanso mandala colorless, ndi osowa kwambiri, kusiyana pakati pawo kudalira akatswiri mosamala kwambiri kuzindikira. Mtundu wofala kwambiri ndi G mpaka L, womwe umadziwikanso kuti pafupifupi wopanda mtundu. Akatswiri adzakhala osavuta kusiyanitsa, koma munthu wamba ndizovuta kusiyanitsa, ngati atayikidwa muzodzikongoletsera ndizovuta kuzizindikira. Mtundu uli pansi pa M, womwe umatchedwanso kuwala kwachikasu, munthu wamba akhoza kusiyanitsa, koma mtengo wake ndi wotchipa kwambiri. Ndipotu, diamondi ali ndi mitundu ina, yotchedwa diamondi yamitundu, ikhoza kukhala yachikasu, pinki, buluu, yobiriwira, yofiira, yakuda, kaleidoscope, koma yosowa kwambiri, yamtengo wapatali kwambiri.

3. Kumveka bwino

Daimondi iliyonse ndi yapadera ndipo imakhala ndi zophatikizika, monga chizindikiro chachilengedwe, ndipo kuchuluka, kukula, mawonekedwe ndi mtundu wa zophatikizika izi zimatsimikizira kumveka kwa diamondi komanso kusiyanasiyana. M'malo mwake, ma diamondi ambiri ophatikizidwa samawoneka ndi maso. Kuchepa kwa zophatikizika mu diamondi, kuwala kumawonekeranso, ndipo diamondi imawala kawiri. Malinga ndi mulingo wa "diamond grading" waku China, kumveka bwino kwa chizindikiritso kuyenera kuchitika mokulira nthawi 10, ndipo magiredi ake ndi awa:

LC kwenikweni ilibe cholakwika

Zochepa kwambiri zamkati ndi zakunja za VVS (akatswiri amayenera kuyang'ana mosamala kuti awapeze)

Zowoneka bwino za VS zamkati ndi zakunja (zovuta kuti akatswiri azipeza)

SI zazing'ono zamkati ndi zakunja (zosavuta kuti akatswiri azipeza)

P ali ndi mawonekedwe amkati ndi akunja (amawonekera m'maso)

Ma diamondi pamwamba pa VVS ndi osowa. Zomwe zili mu VS kapena SI siziwonekanso ndi maso, koma mtengo wake ndi wotsika mtengo, ndipo anthu ambiri amagula. Ponena za P-kalasi, mtengowo ndi wotsika kwambiri, ndipo ngati uli wowala mokwanira komanso wowala mokwanira, ukhoza kugulidwanso.

Zinayi, Dulani

Kudula kumaimira zinthu zambiri, kuwonjezera pa mawonekedwe, kuphatikizapo Angle, gawo, symmetry, kugaya ndi zina zotero. Kudula kwa diamondi kukakhala koyenera, kuwalako kumakhala ngati chonyezimira chagalasi, pambuyo powonekera mbali zosiyanasiyana, zopindika pamwamba pa diamondi, kutulutsa kunyezimira kowala. Kudulidwa kwa diamondi mozama kwambiri kapena kuzama kwambiri kumapangitsa kuti kuwala kuchoke pansi ndikutaya kuwala kwake. Choncho, diamondi zodulidwa bwino mwachibadwa zimakhala ndi mtengo wapamwamba.
