Muaj ntau lub pob zeb muaj nuj nqis thiab ib nrab zoo ib yam li pob zeb diamond ob qho tib si hauv qhov tsos thiab zoo sib xws hauv lub cev. Qee lub pob zeb no yog pob zeb ntuj, tab sis feem ntau ntawm lawv yog cov hluavtaws analogues ntawm cov zaub mov tsis tshua pom muaj nyob hauv qhov xwm txheej. Artificial crystals nyob rau hauv peb lub sij hawm yog zus nyob rau hauv lub laboratory. Qhov kev lag luam no nthuav dav heev.
White Sapphire
Hauv mineralogy, tsuas yog xiav ntau yam ntawm cov ntxhia hu ua sapphire, tag nrho cov seem, tshwj tsis yog ruby, hu ua corundum. Dawb sapphire yog xim tsis muaj xim, ntshiab daim ntawv ntawm alumina thiab tsis muaj oxides ntawm lwm yam hlau uas xim corundum nyob rau hauv ntau ntxoov.
Cov ntau yam dawb ntawm sapphire yog siv los ua cov pob zeb diamond imitation, lossis theej, tsim nyog lwm txoj rau pob zeb diamond kim. Lub pob zeb zoo li pob zeb no yog qhov thib ob tsuas yog pob zeb diamond hauv hardness - 9 ntawm Mohs nplai. Lub pob zeb yuav luag tsis tuaj yeem ua kom puas. Tshwj tsis yog, tau kawg, lub hom phiaj kos nws nrog kev pob zeb diamond lossis corundum.
YWhite Topaz
Dawb topaz, ib lub pob zeb uas muaj nuj nqis ib nrab, txhuas silicate, nrog lub hardness ntawm 8 ntawm Mohs nplai, yog suav tias yog cov khoom tawg yooj yim los ntawm jewelers. Nws muaj ib tug muaj zog glassy luster nrog ib tug me ntsis pearly sheen. Lub pob zeb zoo nkauj zoo li pob zeb diamond tiag tiag. Hauv cov hniav nyiaj hniav kub, tsuas yog tus kws tshaj lij tuaj yeem paub qhov txawv ntawm lawv.
Pob tshab sapphire thiab topaz tsis yog imitations, lawv yuav tsum tau hu ua analogues ntawm pob zeb diamond.
Moissanite
Moissanite yog crystalline daim ntawv ntawm silicon carbide. Tsis tshua muaj, feem ntau pom nyob rau hauv los yog ze meteorite craters. Yuav luag tag nrho cov moissanite siv nyob rau hauv cov hniav nyiaj hniav kub kev lag luam yog ib qho khoom tsim tawm pob zeb.
Vim nws qhov tawv tawv (9.5 ntawm Mohs nplai), cov pob zeb imitation no yog ze tshaj plaws rau pob zeb diamond nyob rau hauv cov nqe lus ntawm durability. Lub pob zeb zoo li pob zeb diamond, tab sis txawv heev ntawm nws hauv cov khoom kho qhov muag.
Moissanite outshines pob zeb diamond. Tsis yog dag. Lub pob zeb zoo kawg nkaus cuam tshuam lub teeb. Lub dispersion coefficient ntawm moissanite ho ntau tshaj qhov dispersion coefficient ntawm pob zeb diamond. Ib lub teeb ntawm lub teeb dawb yog decomposed rau hauv monochromatic rays ntawm tag nrho cov spectrum ntawm zaj sawv. Lub pob zeb ci ntsa iab zoo li lub teeb ntawm neon tshaj tawm, thiab qhov no me ntsis tsis meej pem tam sim ntawd ntxeev siab rau tus qauv. Txawm li cas los xij, ntau tus neeg feem ntau xa mus rau moissanite ua pob zeb diamond dag.
Rau cov neeg nyiam ntxim nyiam yam tsis muaj tus nqi sib tw ntawm ib nrab xyoo cov nyiaj hli, qhov no yog pob zeb zoo meej.
Cubiczirconium
Thawj thawj zaug ua ke hauv cubic system hauv xyoo 1970 rau cov kev xav tau ntawm kev lag luam kho qhov muag, lub zirconium dioxide siv lead ua tam sim ntawd nyiam cov xim ntawm jewelers nrog nws lub peev xwm ua lub pob zeb diamond simulant. Nyob rau hauv lub Soviet Union, nws yog hu ua fianite, thev naus laus zis tau tsim los ntawm cov kws tshawb fawb los ntawm lub koom haum Physical Institute ntawm Academy of Sciences. Nyob rau sab hnub poob, lub pob zeb hu ua zirconium, zirconite thiab yog abbreviated CZ.
Tshuaj yaj-loj hlob hauv chav kuaj hauv qhov tsis muaj qhov txwv thiab ntawm tus nqi pheej yig, cov siv lead ua tau raug txhais tam sim ntawd raws li "pob zeb diamond rau cov neeg".
Hnub no nws yog ib qho ntawm cov khoom siv pob zeb nrov tshaj plaws. Nws tuaj yeem pom nyob rau hauv cov khoom lag luam ntawm cov khoom lag luam nto moo thiab cov khoom tsim khoom kim heev.
Lub pob zeb muaj cov khoom kho qhov muag ze heev rau cov pob zeb diamond. Tab sis tsis tsuas yog cov khoom tshwj xeeb no tau pab txhawb rau kev siv ntau ntawm cubic zirconia hauv cov hniav nyiaj hniav kub. Lub pob zeb yog qhov pheej yig heev: ib carat cubic zirconia raug nqi txog $ 20 ntawm lub khw hauv ntiaj teb. Cov cuab yeej loj hlob yog xws li cov siv lead ua kev loj hlob ntawm 8 mus rau 10 hli / teev.
Qhov sib txawv tseem ceeb ntawm cubic zirconia thiab pob zeb diamond yog hardness, nws yog 8.5 ntawm Mohs nplai. Lub pob zeb tau yooj yim puas thiab sai sai, poob nws cov luster. Los ntawm lub ntiajteb txawj nqus, cubic zirconia hnyav dua li pob zeb diamond.
Pom pom lub pob zeb twg hauv cov hniav nyiaj hniav kub, zirconium lossis pob zeb diamond, tuaj yeem tsuas yogpaub connoisseur. Artificially zus crystals yeej ib txwm flawless, lawv tsis muaj qhov tsis xws luag uas feem ntau pom nyob rau hauv ntuj gemstones. Los ntawm txoj kev, qhov no yog lub ntsiab lus tsom xam siv los ntawm jewelers. Sib piv lub pob zeb diamond thiab cubic zirconia tsis xav tau kev soj ntsuam ntev thiab nyuaj. Yog hais tias lub gemstone zoo li lub pob zeb diamond tab sis tsis muaj qhov tsis zoo thiab zoo tag nrho, nws yog qhov tsis xav tau cubic zirconia.
Zirconium yog tus thawj coj hauv kev siv los ua cov hniav nyiaj hniav kub stylish nrog kev tsim qauv. Lub pob zeb hauv cov hniav nyiaj hniav kub tuaj yeem saib ob qho tib si elegant thiab siab phem, nyob ntawm qhov loj thiab xim ntawm cov siv lead ua.
Zionite siv lead ua kev loj hlob thev naus laus zis tau txhim kho ntau xyoo mus rau qhov uas cov xim ntawm cov muaju sib txawv ntawm pob tshab mus rau xim dub.
Pomegranate
Cov xim tsis muaj xim tsis pom ntawm cov khoom ntuj tsim. Tab sis cov khoom siv hluavtaws ntau yam hauv chav kuaj tuaj yeem tsim nrog cov yam ntxwv xim.
Txhua cov xim tsis muaj xim garnet yog cov khoom siv dag zog thiab siv rau hauv cov hniav nyiaj hniav kub ua ib qho piv txwv ntawm pob zeb diamond. Nws yog tsuas yog siv nyob rau hauv tsej, necklaces, pendants thiab pendants, txij li thaum garnet yog ntau softer tshaj pob zeb diamond - lub hardness ntawm hluavtaws garnet ranges ntawm 7.5 mus rau 8.5 ntawm lub Mohs nplai. Nws qhov txiaj ntsig zoo li lub pob zeb diamond simulant yog nws txoj kev ci ntsa iab: ntau yam tsis muaj xim ntawm cov ntxhia muaj pob zeb diamond brilliance.
Spinel
Ib qho ntxhia tsis tshua muaj, sib xyaw ntawm txhuas thiab magnesium oxides. Pob tshab, tsis muaj xim ntau yam ntawm spinel yog qee zaum siv los ua cov pob zeb diamond. Lub pob zeb zoo li pob zeb muaj lub ci ci ci ntsa iab thiab cov khoom siv kho qhov muag zoo.
Zoo li txhua qhov hloov pauv, spinel yog softer (kwv yees 8.0 ntawm Mohs nplai) dua li pob zeb diamond tiag.
Rutile
Rutile yog cov ntxhia ntuj, ntshiab titanium dioxide. belongs rau qeb ntawm semi-precious thiab ornamental pob zeb. Muaj kev tsim kho kev lag luam rau kev tsim cov khoom siv hluavtaws ntawm rutile. Nyob rau hauv qhov xwm txheej, tsis muaj xim txawv ntawm lub pob zeb tsis pom, tab sis nyob rau hauv lub chaw kuaj mob nws yog ib qho tseem ceeb kom loj hlob ib tug siv lead ua tsis muaj impurities. Qee zaum siv los ua pob zeb diamond simulated.
Qhov no yog cov ntxhia mos, nrog rau qhov nyuaj ntawm Mohs nplai ntawm 6.0-6.5. Cov tawv tawv no suav tias tsis txaus rau cov hniav nyiaj hniav kub ntxig rau hauv cov hlau kim, vim tias txawm tias cov hmoov av tuaj yeem tawm khawb rau lawv nrog kev sib txhuam. Rutile crystals feem ntau yog siv los tsim cov hniav nyiaj hniav kub rau cov neeg siv khoom loj.
Xaiv: pob zeb diamond lossis…
Muaj tseeb tiag, pob zeb diamond tuaj yeem yog qee tus ntxhais cov phooj ywg zoo tshaj plaws. Tab sis tsis yog tag nrho thiab tsis tas li.
Yog, lawv zoo nkauj, ruaj khov, zoo nkauj ci ntsa iab. Lawv yog timeless thiab tawm ntawm fashion. kim kim thiab classic heev yog tias koj yog cov ntxhais niaj hnub uas xav hnav ib yam dab tsi txawv ntawm nws ntiv tes ntiv tes.
Tau ntau pua xyoo dhau los tau muaj txoj cai tswjfwm tsis zoo: cov poj niam hnub nyoog qis dua peb caug tsib tsis txhob hnav pob zeb diamond. Lub pob zeb yog lub cim ntawm kev ua tiav ntawm nws tus tswv ntawm "Balzac hnub nyoog", thiabtus poj niam zoo li cas es npaj siab lees tias laus?
Tsis txhob hnav pob zeb diamond txog 5 teev tsaus ntuj. Lub pov haum yav tsaus ntuj, lub pob zeb diamond qhia tawm nws qhov ntxim nyiam tshaj plaws thaum raug teeb pom kev zoo ntau yam, txawm tias nws yog taws tswm ciab lossis lub teeb txuag hluav taws xob niaj hnub.
Kev cai ntawm kev muab tus nkauj nyab lub nplhaib sib koom nrog lub pob zeb diamond, tsis poob, tau tshwm sim los ntawm kev ntse thiab tsom mus rau kev lag luam los ntawm De Beers hauv peb caug xyoo XX. Qhov no yog tib neeg kev cog lus ua. Lub nplhaib pob zeb diamond tau hnav txhua lub sijhawm, thiab qhov no tsis yog coj tus cwj pwm phem.
Niaj hnub nimno cov hniav nyiaj hniav kub hnav khaub ncaws tsis yog categorical. Qhov tseem ceeb ntawm kev xaiv cov hniav nyiaj hniav kub niaj hnub: kev nkag siab ntawm style thiab kev faib ua feem. Lub pob zeb diamond loj hauv ib lub nplhaib ntawm tes ntawm tus poj niam taug kev aub yug yaj hauv lub ris tsho zoo li tsis txaus ntseeg zoo li lub tsho ua luam dej ntawm kev caij ski.
