Raws li lub pov haum cov ntaub ntawv uas muaj siab plasticity nyob rau hauv lub qhov muag ntawm lub pov haum craftsmen, citrine yog ib tug nquag qhua rau zoo nkauj lub pov haum txiav.
Thaum pib, nws tau hu ua "Pob Zeb Hloov Hloov" rau nws cov khoom sau los ntawm cov khoom siv pob zeb zoo nkauj.Citrine yuav tsis yog qhov ci tshaj plaws.Tab sis nws kuj yog ib qho ntawm cov pob zeb tsis muaj xim siv los "hloov" pob zeb diamond.
Hauv ob peb xyoos dhau los, Citrine tau dhau los ua cov khoom lag luam qib siab zoo rau cov jewelers, thiab cov citrine kab ua piv txwv lub npe "hloov pob zeb diamond" thiab tshwm nyob rau hauv lub qhov muag ntawm jewelers raws li nws tus kheej.
Feem ntau ntawm cov lo ntsiab muag ntawm kev ua lag luam niaj hnub no yog los ntawm Mexico, tshwj xeeb tshaj yog los ntawm Chacas hauv San Luis Potosi.Lwm cov sapphires muaj nyob hauv Bolivia, nrog rau hauv Myanmar, Nyiv, Madagascar thiab Russia.
Yog Cycitrine yog haiv neeg tsawg, Tsis yog lub ntsiab dej;Nws yog lub pov haum tsis muaj xim.Cov hauv qab no yog cov pob zeb tsis muaj xim uas feem ntau siv hauv cov hniav nyiaj hniav kub.Txheeb los ntawm tus nqi lag luam: tsis muaj xim pob zeb diamonds;Dawb sapphires;Dawb oysters thiab dawb crystals
Ob leeg yog cov tsis muaj xim.Dhau li ntawm kev tsim khoom Yuav ua li cas cov kev cai huab cua cuam tshuam rau tus nqi sib txawv?
