Ma diamondi akhala akukondedwa ndi anthu ambiri, anthu nthawi zambiri amagula diamondi monga mphatso za tchuthi kwa iwo eni kapena ena, komanso zofunsira ukwati, ndi zina zotero, koma pali mitundu yambiri ya diamondi, mtengo wake sufanana, musanagule diamondi. , muyenera kumvetsetsa mitundu ya diamondi.
Choyamba, malinga ndi mapangidwe a magawano
1. Mwachibadwa diamondi zopangidwa
Ma diamondi okwera mtengo kwambiri pamsika nthawi zambiri amapangidwa ndi crystallization pakapita nthawi m'malo otentha kwambiri komanso kupanikizika (nthawi zambiri kusowa kwa mpweya), ndipo diamondi zakale kwambiri zomwe zimapezeka ndi zaka 4.5 biliyoni. Daimondi yotereyi ndi yamtengo wapatali chifukwa siipezeka kawirikawiri.
2. Ma diamondi opangira
Ndi chitukuko cha sayansi ndi luso lamakono, pali diamondi zambiri zopangira pamsika, ndipo anthu ambiri amatha kupanga ma diamondi onyenga kudzera mu galasi, spinel, zircon, strontium titanate ndi zipangizo zina, ndipo mtengo wa diamondi wotere nthawi zambiri umakhala wotsika kwambiri. Koma ndizofunika kudziwa kuti ena mwa ma diamondi opangirawa amaoneka bwino kuposa diamondi zopangidwa mwachilengedwe.
Chachiwiri, malinga ndi kalasi ya diamondi 4C
1. Kulemera
Malinga ndi kulemera kwa diamondi, diamondi ikakula, diamondiyo imakhala yamtengo wapatali. Chigawo chomwe chimagwiritsidwa ntchito poyeza kulemera kwa diamondi ndi carat (ct), ndipo carat imodzi ndi yofanana ndi ma gramu awiri. Zomwe timazitcha kuti mfundo 10 ndi mfundo 30 ndikuti 1 carat imagawidwa m'magawo 100, iliyonse yomwe ili ndi mfundo imodzi, ndiye kuti, mfundo 10 ndi 0.1 carats, 30 ndi 0,3 carats, ndi zina zotero.
2. Mtundu
Ma diamondi amagawidwa ndi mtundu, womwe umatanthawuza kuya kwa mtundu osati mtundu wa mtundu womwe uli pansipa. Malinga ndi kuya kwa mtundu wa diamondi kuti mudziwe mtundu wa diamondi, kuyandikira kwa diamondi kumakhala kopanda mtundu, kumapezekanso kwambiri. Kuchokera ku ma diamondi a giredi D mpaka ma diamondi a giredi la Z akuda kwambiri, DF ilibe mtundu, GJ imakhala yopanda mtundu, ndipo diamondi ya K-grade imataya mtengo wake.
3. Kumveka bwino
Ma diamondi amagawidwa momveka bwino, zomwe ziri zenizeni momwe diamondi iliri yoyera. Kuyera kwa diamondi kumatha kuwonedwa pansi pa maikulosikopu khumi, ndipo zophophonya zowoneka bwino, zokopa, ndi zina zambiri, zimatsitsa mtengo wake, ndi mosemphanitsa. Malinga ndi kumveka kwa diamondi zazikulu zimagawidwa m'mitundu 6, motero FL, IF, VVS, VS, S, I.
4. Dulani
Gawani diamondi kuchokera kudulidwa, kudulidwa bwino, momwe diamondi imawonetsera kuwala kuti ikwaniritse gawo langwiro. Mawonekedwe odziwika bwino a diamondi ndi mtima, masikweya, oval, ozungulira ndi pilo. Pachifukwa ichi, diamondi amagawidwa m'mitundu isanu: EX, VG, G, FAIR ndi POOR.
Chachitatu, malinga ndi gawo la mtundu wa diamondi
1, diamondi yopanda mtundu
Ma diamondi opanda mtundu amatanthawuza mtundu wa diamondi wopanda mtundu, pafupifupi wopanda mtundu kapena wonyezimira wa diamondi wopepuka wachikasu, ndipo gulu la diamondi lopanda utoto ndilotchulidwa pamwambapa molingana ndi kuya kwa mtundu kugawikana.
2. Ma diamondi amitundu
Chifukwa cha mapangidwe a diamondi amitundu ndikuti kusintha kosawoneka bwino mkati mwa diamondi kumatsogolera ku mtundu wa diamondi, ndipo malingana ndi mtundu wosiyana wa diamondi, diamondiyo imagawidwa m'mitundu isanu. Pankhani ya mtengo, imagawidwa mu diamondi zofiira, diamondi za buluu, diamondi zobiriwira, diamondi zachikasu ndi diamondi zakuda (kupatula diamondi yapadera).
