Guhitamo impeta yo gusezerana birashobora kuba umurimo utoroshye. Hano hari umubare wamahitamo iyo bigeze kumiterere nubunini nuburyo butandukanye bwamabara atangwa… kandi nibyo mbere yuko utekereza ikintu cyose gisobanutse, karatike no gukata! Kugirango utangire munzira iganisha ku gusobanura amagambo ya diyama kugirango ubashe kugura neza, dore ibintu byose ukeneye kumenya kuri diyama y'amabara.
Diyama Yera
Diyama iraboneka mumabara atandukanye, harimo amabuye ya 'ibara ritagira ibara' inzira zose zinyuze mumabara yijimye, ubururu, umutuku nibindi. Kugirango umenye agaciro ka diyama no korohereza abaguzi kubyumva, diyama yera cyangwa 'idafite ibara' itondekanya ukurikije igipimo cyamabara ya GIA kuva D kugeza Z.
Mubisanzwe, diyama yagizwe 'D' ibara ryayo ifite agaciro gakomeye kuko ifatwa nka diyama yera 'yera', bityo igashakishwa cyane kandi ihenze. Mugihe ugenda munsi yikigereranyo, diyama itangira guhinduka umuhondo muto, kugeza, munsi yikigereranyo, diyama yijimye yinjiza Z amanota.
Ariko, diyama y'amabara ntabwo buri gihe ari ikintu kibi. Mubyukuri, amabara meza, yifuzwa na benshi abaho gusa muri kamere mubihe bidasanzwe… ntabwo rero buri gihe akurikiza ko diyama itagira ibara ari nziza! Mubisanzwe bibaho diyama yamabara yijimye, amacunga nubururu bugaragara, kurugero, ni gake cyane kuruta diyama idafite ibara. Kandi, nkigisubizo, diyama yamabara yategetse bimwe mubiciro biri hejuru kubutare muri cyamunara kwisi.
Nigute Diyama Yamabara Yakozwe?
Diyama y'amabara igura ibara ryayo iyo ikozwe mwisi. Diyama idafite ibara, 'cyera' igizwe na karubone 100%, bivuze ko ntakindi kintu kiri mumurongo wa karubone. Diyama y'amabara, kurundi ruhande, yabonye ibindi bintu bigira uruhare mugihe cyo kubikora, nka azote (itera diyama yumuhondo), boron (itanga diyama yubururu) cyangwa hydrogène (itanga diyama itukura na violet).
Birashoboka kandi ko diyama ibona amabara ashakishwa cyane bitewe nigitutu cyinshi cyangwa ubushyuhe nkuko biri gukorwa. Kandi, birazwi kandi ko imirasire isanzwe itera diyama gukura mumabuye yamabara, bingana na diyama yubururu nicyatsi kiboneka mubice bimwe byisi. Rero, hari inzira nyinshi zuburyo diyama ishobora kubona amabara meza, bigatuma agira agaciro karenze kure cyane bagenzi babo!
Amabuye ya Diyama ahenze cyane kwisi
Muri 2014, diyama yinyenyeri yijimye yagurishijwe muri cyamunara miliyoni 83! Yari diyama nziza, yuzuye amabara ya diyama yumvikana neza kandi ipima karat 59.40, imaze amezi arenga 20 gucukura muri Afrika yepfo.
Nyamara, diyama itukura mubyukuri ni amabuye y'agaciro ahenze kwisi yose, hamwe nigiciro kirenga miliyoni imwe kuri karat. Muri 2014, umutima wa karat 2.09 ufite diyama itukura yagurishijwe miliyoni 3.4 muri Hong Kong. Rero, hamwe na diyama zitukura zitarenga 30 zanditse kwisi yose (kandi inyinshi murizo ntoya ya kimwe cya kabiri cya karat), diyama itukura niyo idakunze kubaho kandi ihenze muri byose.
