Synthetic neon xiav beryllium - recrystallized - Be3Al2 (SiO3) 6 - video
Txheem:
Kev siv tshuab siab tam sim no tso cai rau kev tsim khoom ntawm txhua hom neon xiav hluavtaws 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 neon xiav beryl hauv cov xim uas tsis zoo rau cov pob zeb ntuj, tab sis muaj ntau dua hauv lwm cov zaub mov. Cov piv txwv no suav nrog lub ci ntsa iab hack tourmaline thiab qhov sib sib zog nqus xiav Paraiba tourmaline, uas muaj nuj nqis heev los ntawm cov jewelers rau lawv qhov tsis tshua muaj txaus ntseeg 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.
