Emerald yog ib qho ntawm lub pov haum tshaj plaws thiab zoo nkauj. Nws yog txaus siab rau nws cov xim nplua nuj ntsuab sib txawv. Qhov tob tob ntawm kab npauj kab tau paub txog tib neeg txij puag thaum ub los. Cov gems no muaj nqi nrog cov peev xwm zoo nkauj thiab kho. Thiab tseem muaj ntau tus neeg ntxiv uas xav mus yuav cov txiv huab tais dua li cov pob zeb lawv tus kheej. Yog li ntawd, tus naj npawb ntawm cov khoom cuav tsis yog qhov xav tsis thoob.

Cov Lus Qhia
Kauj ruam 1
Tso lub pob zeb rau ntawm daim ntawv dawb thiab ntsuas nws cov xim. Txhua tus kab tho puav leej muaj xim nyob rau ntau qhov ntxoov ntsuab. Yog tias muaj lub suab daj ua xim daj nyob rau hauv cov xim, feem ntau yuav nyob rau hauv pem hauv ntej ntawm koj lub ntsuab garnet lossis peridot. Cov xim ntsuab ntawm kab tho muaj qhov ntsej pleev xiav.
Kauj ruam 2
Tig lub pob zeb hauv qab lub teeb ci. Them sai sai rau qhov sib txawv. Lo lus no gemologists hu flashes lossis cov taws teeb uas tsim vim muaj ntau yam kev sib xyaw. Emeralds muaj qib kev tawg qis, yog li pob zeb ntuj muab me me "hluav taws". Yog tias lub pov haum taws teeb thiab shimmers, feem ntau yuav nyhav zirconia nyob pem hauv ntej ntawm koj.
Kauj ruam 3
Txheeb zeb nrog lub ntsuas hluav taws xob. Qhov ntsuas refractive ntawm emeralds yog kwv yees li 1.58.
Kauj ruam 4
Cov xim ntsuab, rau cov kab tho ntoo yog qhov muaj nuj nqis, tshwm sim vim yog qhov muaj ntau ntawm chromium hauv cov ntxhia. Yog li ntawd, kab tho pom tshwm xim av lossis xim liab nyob rau hauv lub taub lim xim. Tab sis cov lim yuav tsis tso cai rau koj kom paub qhov txawv ntawm cov kab npoo ntuj ntawm ib qho khoom neeg tsim.
Kauj ruam 5
Cov tshuaj fluorite ntsuab muaj cov duab ntxoo zoo ib yam nyob hauv qab lim, tab sis nws yog softer ntau dua li kab ntxig thiab yog yooj yim khawb txawm yog iav. Cov tshuaj fluorite nyob rau hauv duab tshav teeb ci fluoresces nrog lub teeb nrig violet. Hauv cov kab ntxig, ob leeg luminescence thiab fluorescence yog tsawg thiab feem ntau muaj xim liab lossis xim ntsuab.
Kauj Ruam 6
Txheeb xyuas cov npoo ntawm cov pob zeb kom zoo zoo. Ntau qhov ua raws ntawm cov kab tho, hu ua "doublet" lossis "triplet" Nws yog zoo li lub qhaub cij ntawm iav, ntsuab epoxy cob thiab nyias txiav ntawm cov kab tho zoo. Thaum saib los ntawm sab, qhov cuav yog pom tseeb.
Kauj Ruam 7
Ua tib zoo mloog rau "hnav" ntawm cov npoo. Lub hardness ntawm Mohs nplai ntawm emeralds yog qhov siab heev, yog li lawv nyob twj ywm rau lub sijhawm ntev. Iav imitations hnav tawm sai sai. Qhov no yog pom meej hauv qab ntawm daim iav muaj zog.
Kauj ruam 8
Cov kab tho ntuj ib txwm muaj nyob nrog txawv teb chaws. Lawv pom meej hauv qab lub khob tsom iav lossis lub tsom tsom iav. Yog li ntawd, emeralds tshwm me ntsis huab. Tag nrho cov kev tawg, npuas thiab plaub tsis xeb cov zaub mov. Cov Jewelers hu cov nyhuv no yog lo lus "Jardin" (los ntawm Fab Kis rau "vaj"). Xws li qhov tsis xws luag yuav luag tsis pom nyob hauv cov pob zeb zus.
