Synthetic ob-xim beryllium - recrystallized - Be3Al2 (SiO3) 6 - video
Txheem:
Advanced thev naus laus zis tam sim no tso cai rau kev tsim khoom ntawm txhua hom hluavtaws bicolor beryllium.
Yuav cov pob zeb ntuj hauv peb lub khw
Emerald ntawm cov hoob kawm, tab sis kuj tag nrho cov ntau yam ntawm lwm yam beryllium xim, xws li liab los yog liab bixbite, daj ntseg liab morganite, beryllium ntsuab ntawm tej xim saturation, raws li zoo raws li xiav-ntsuab (Paraiba) los yog aquamarine. Cov ntau yam ntawm beryllium no tsis tshua muaj, thiab qhov loj ntawm cov pob zeb ntuj tsis tshaj 1-3 carats. Yog li ntawd, cov qauv dawb huv ntawm cov qauv xim uas hnyav tshaj kaum carats tuaj yeem raug cais raws li cov pob zeb sib sau.
Tsis tas li ntawd, thev naus laus zis ua rau nws tuaj yeem loj hlob hluavtaws ob-xim beryls nrog cov xim uas tsis yog yam ntxwv ntawm cov pob zeb ntuj, tab sis muaj ntau dua hauv lwm cov ntxhia. Cov piv txwv no suav nrog ci liab caws pliav tourmaline thiab sib sib zog nqus xiav Paraiba tourmaline, uas muaj nuj nqis heev los ntawm jewelers rau lawv qhov tsis txaus ntseeg tsis tshua muaj thiab xim tshwj xeeb.
Cov ntaub ntawv zoo li no yog nrov nrog cov tuam txhab nyiaj txiag muaj tswv yim uas muab cov hniav nyiaj hniav kub ntawm cov qauv tshiab thiab qub rau cov neeg yuav khoom zoo.
