Diyama yamye ikundwa nabantu benshi, mubisanzwe abantu bagura diyama nkimpano zikiruhuko kuri bo cyangwa kubandi, ndetse no kubasaba gushyingirwa, nibindi, ariko hariho ubwoko bwinshi bwa diyama, igiciro ntabwo ari kimwe, mbere yo kugura diyama , ugomba kumva ubwoko bwa diyama.
Ubwa mbere, ukurikije ishingwa ryamacakubiri
1.Bisanzwe diyama
Diyama ihenze cyane ku isoko muri rusange ikorwa no gutondekanya igihe mu bihe by'ubushyuhe bukabije n'umuvuduko ukabije (ubusanzwe kubura ogisijeni), kandi diyama ya kera yabonetse ifite imyaka miliyari 4.5. Ubu bwoko bwa diyama buri hejuru cyane mubyagaciro kuko ntibisanzwe.
2. Diyama yubukorikori
Hamwe niterambere ryubumenyi nubuhanga, ku isoko hari diyama nyinshi zubukorikori ku isoko, kandi abantu benshi barashobora gukora diyama yigana binyuze mu kirahure, spinel, zircon, strontium titanate nibindi bikoresho, kandi agaciro ka diyama muri rusange ni gake. Ariko birakwiye ko tumenya ko zimwe murizo diyama zubukorikori zisa neza kuruta diyama isanzwe.
Icya kabiri, ukurikije icyiciro cya diyama 4C
1. Uburemere
Ukurikije uburemere bwa diyama, uko uburemere bwa diyama, niko diyama ifite agaciro. Igice cyakoreshejwe mu gupima uburemere bwa diyama ni karat (ct), na karat imwe ihwanye na garama ebyiri. Icyo dusanzwe twita amanota 10 n amanota 30 nuko karat 1 igabanijwemo ibice 100, buri kimwe kikaba ingingo imwe, ni ukuvuga ko amanota 10 ari karat 0.1, amanota 30 ni karat 0.3, nibindi.
2. Ibara
Diyama igabanijwemo ibara, ryerekeza ku burebure bw'amabara kuruta ubwoko bw'amabara hepfo. Ukurikije ubujyakuzimu bw'ibara rya diyama kugirango umenye ubwoko bwa diyama, uko diyama yegereye ibara, ni nako yegeranya. Kuva D Diyama yo mu rwego rwa D kugeza kuri Z urwego rwa diyama rugenda rwijimye, DF idafite ibara, GJ isa nkaho itagira ibara, na diyama yo mu rwego rwa K itakaza agaciro kayo.
3. Kugaragara
Diyama igabanijwe kubisobanutse, mubyukuri nukuntu diyama isukuye. Ubuziranenge bwa diyama burashobora kugaragara munsi ya microscope inshuro icumi, kandi byinshi cyangwa byinshi bigaragara inenge, gushushanya, nibindi, hasi agaciro, naho ubundi. Ukurikije ubusobanuro bwa diyama nini igabanijwemo ubwoko 6, FL, NIBA, VVS, VS, S, I.
4. Kata
Gabanya diyama ukata, nibyiza gukata, niko diyama ishobora kwerekana urumuri kugirango ugere ku kigero cyiza. Imiterere ya diyama ikunze kugaragara ni umutima, kare, oval, uruziga n'umusego. Ni muri urwo rwego, diyama igabanijwemo ubwoko butanu: EX, VG, G, FAIR na POOR.
Icya gatatu, ukurikije igabana rya diyama
1, diyama idafite ibara
Diyama idafite ibara yerekeza ku bwoko butagira ibara, hafi butagira ibara cyangwa hamwe na diyama y'umuhondo yoroheje, kandi gushyira diyama idafite ibara ni byo byavuzwe haruguru ukurikije uburebure bw'amabara kugirango ugabanye.
2. Diyama y'amabara
Impamvu yo gukora diyama yamabara ni uko impinduka zoroshye imbere muri diyama ziganisha ku ibara rya diyama, kandi ukurikije ibara ritandukanye rya diyama, diyama igabanijwemo ubwoko butanu. Kubijyanye nigiciro, igabanijwemo diyama itukura, diyama yubururu, diyama yicyatsi, diyama yumuhondo na diyama yumukara (usibye diyama idasanzwe).
