Alexandrite tseem yog ib lub pov haum hluas heev, vim nws tau pom tsuas yog nyob rau xyoo pua cuaj xwb.
Natural pob zeb yog cov ntxhia pob zeb tsis tshua muaj thiab yog li muaj txiaj ntsig zoo thoob plaws ntiaj teb, uas tau nthuav tawm hauv nws cov nqi ntawm kaum tawm txhiab daus las. Ib tug feature ntawm lub pob zeb no yog nws lub peev xwm, nyob ntawm seb lub teeb pom kev zoo, hloov nws cov xim - pleochroism - los ntawm emerald ntsuab mus rau kaj liab. Lub purer cov zis xim, qhov kim dua alexandrite.
Ural pob zeb yog siv dav hauv kev tsim cov hniav nyiaj hniav kub, uas xav tsis thoob nrog nws txoj kev zoo nkauj thiab kev tshav ntuj. Nws kuj pom cov ntawv thov hauv kev tshawb fawb - quantum mechanics, tshuaj, cosmetology (synthetic analogues).
History ntawm lub pov haum Ural
Alexandrite tau pom nyob rau hauv Urals hauv 1934 nyob rau kaum rau xyoo ntawm Emperor Alexander II los ntawm Finnish geologist N. Nordenschild. Txij li thaum nws yog los ntawm lub hnub nyoogTsar, lub pob zeb tau muab lub npe hu ua nws thiab nthuav tawm rau tus txiv neej hnub yug los ntawm cov hniav nyiaj hniav kub craftsman Perovsky.
Tab sis thawj qhov hais txog Peacock's Eye nugget tau pom nyob rau hauv plaub txhiab xyoo Indian treatise Mahabharata.
Cov pob zeb no tshwj xeeb tshaj yog nrov ntawm cov neeg muaj koob meej nyob rau xyoo pua cuaj thiab raug nqi zoo heev.
Hauv tebchaws Russia, txij li xyoo 1980, lawv pib loj hlob thiab tsim cov khoom siv hluavtaws - fakes rau ntuj pob zeb, tus nqi uas pheej yig dua ob peb zaug.
Tam sim no, lub ntsiab ntim ntawm kev tsim khoom poob ntawm cov nyiaj tso nyiaj loj nyob hauv Brazil, Tanzania, Sri Lanka, Africa thiab Russia (Malyshevskoye teb). Ural alexandrites yog cov ntxhia muaj txiaj ntsig tshaj plaws, vim lawv muaj xim ci thiab kev hloov pauv ntawm ib qho mus rau lwm qhov.
Type of alexandrites
Hauv qhov xwm txheej, koj tuaj yeem pom cov hom pob zeb no:
- Tsimofan, nyob rau hauv tib neeg hu ua miv qhov muag. Nws tsis tshua pom muaj. Lub teeb nyhuv ntawm no ntau yam yog tau vim lub fact tias ib tug loj tus naj npawb ntawm me me inclusions nyob rau hauv cov ntxhia pob zeb yog oriented nyob rau hauv tib txoj kev. Yog li ntawd, nyob rau hauv tej yam illumination, ib tug kaj kab txaij zoo li ib tug miv lub qhov muag tshwm nyob rau hauv nruab nrab ib feem ntawm lub pob zeb.
- Ural alexandrite yog lub pob zeb tseem ceeb tshaj plaws, cov xim uas hloov ntawm ntsuab mus rau liab.
- Hauv Is Nrias teb, ntau yam yog mined uas hloov xim los ntawm daj mus rau liab.
Tshuaj muaj pes tsawg leeg ntawm Ural lub pov haum
BCov ntxhia pob zeb muaj xws li chromium (muab ntsuab), titanium thiab hlau (liab ntsiab). Nws yog cov khoom ntawm chromium ions thiab siv lead ua lattice uas ua rau lub pob zeb hloov xim. Vanadium tsis tshua pom muaj nyob hauv cov koom nrog, uas tseem muaj peev xwm cuam tshuam kev hloov pauv ntawm alexandrite.
Ural ntuj pob zeb muaj cov mis BeAI2O4, uas yog vim muaj tshuaj lom neeg muaj pes tsawg leeg ntawm complex beryllium aluminium tetroxide, thiab yog ib hom chrysoberyl ntxhia.
Lwm qhov tshwj xeeb ntawm cov pob zeb no yog nws qhov nyuaj, uas siab dua li ntawm emerald. Nws yog yim thiab ib nrab units raws li Moss nplai.
Qhov ntom ntawm alexandrite yog txiav txim siab los ntawm rab rawg 3, 5-3, 8 g / cm3, thiab lub teeb ci yog 1, 74-1, 76.
Nyob zoo
Cov kws kho mob ib txwm hais tias nws tsim nyog ua tib zoo saib xyuas cov khoom kho mob ntawm alexandrite:
- tso tseg los ntshav;
- nws ntxuav cov ntshav;
- siv hauv kev kho cov hlab ntsha thiab lub plawv;
- zoo cuam tshuam rau kev ua haujlwm ntawm tus po thiab daim siab;
- pab cov kab mob pancreas;
- kho mob cawv;
- tswj kev mob hlwb.
tshuaj ntsuab qhia kom hnav cov hniav nyiaj hniav kub ua nrog lub pob zeb no, piv txwv li, lub nplhaib nrog Ural alexandrite.
Magic endows cov pob zeb no nrog lub peev xwm los txhim kho qhov zoo ntawm ib tus neeg:cov tsis muaj zog subjugates nws lub hwj chim thiab muaj peev xwm rhuav tshem, thiab lub zog - txhawb nqa thiab pab kov yeej teeb meem.
Nws tseem ntseeg tias lub pov haum no muaj cov khoom sib txawv nyob ntawm lub sijhawm nruab hnub: thaum yav tsaus ntuj nws txhim kho kev xav khib thiab mob siab rau, thaum tav su - kev ntseeg siab thiab kev thaj yeeb.
Thiab txij li kev tua neeg ntawm Lavxias teb sab huab tais nyob rau hauv Russia, kev lig kev cai tau tshwm sim ntawm hnav lub pob zeb no los ntawm poj ntsuam los ua pov thawj ntawm kev poob ntawm ib tug neeg hlub.
Nyob hauv Is Nrias teb, lub nugget suav hais tias yog lub cim ntawm kev thaj yeeb nyab xeeb thiab hnav los ntawm cov txiv plig.
Rules for stone care
Yuav kom cov khoom lag luam ua los ntawm cov ntxhia muaj txiaj ntsig mus ntev, nws yuav tsum ua raws li ntau txoj cai:
- yuav tsum tshem cov hniav nyiaj hniav kub thaum ntxuav ib ncig ntawm lub tsev;
- txhawm rau ntxuav cov khoom, koj yuav tsum siv cov xab npum thiab dej kub - tsis muaj tshuaj lom;
- siv cov ntaub mos mos, tsis muaj lint-dawb rau polishing;
- thaum ua haujlwm hauv chav kuaj lossis hauv kev tsim khoom, tsis txhob hnav cov khoom ntawm koj txhais tes.
Yuav ua li cas hnav alexandrite: kos npe
Kev sib xyaw ua ke ntawm cov hniav nyiaj hniav kub thiab khaub ncaws yuav zoo kawg nkaus rau kev tsim cov duab. Thaum hnav cov khoom los ntawm cov ntxhia no, koj yuav tsum ua raws li cov lus qhia hauv qab no:
- cov cim qhia tias koj yuav tsum tsis txhob hnav cov ntxhia ua cov hniav nyiaj hniav kub ywj pheej (qhov no tuaj yeem ua rau muaj hmoo zoo), piv txwv li, qhwv ntsej nrog Ural alexandrite yuav tsum tau ua ke nrog cov nplhaib uas lwm cov pob zeb tau ntxig;
- khoom nrog lub pov haum no muaj nqismuab tso ua ntej, tshem tawm kawg;
- Koj tuaj yeem hnav alexandrite tsis hais lub sijhawm nruab hnub - nws ib txwm zoo nkauj, tab sis tshwj xeeb tshaj yog zoo nkauj hauv cov teeb pom kev zoo, thaum nws hloov xim liab;
- hlau zoo tshaj plaws rau kev teeb tsa nugget yog kub, uas txhim kho nws txoj kev zoo nkauj thiab ci ntsa iab;
- tus txiv neej saib thiab kev ntseeg siab ntawm tus kheej yuav ua rau muaj kev sib deev muaj zog txiv neej lub nplhaib kub nrog Ural alexandrite ua ke nrog cov khoom lag luam kim kim.
Gem price
Natural gem muaj tus nqi siab heev, nyob ntawm nws cov xim, kev ua cov hniav nyiaj hniav kub, muaj qhov tsis xws luag. Raws li txoj cai, nws tsis tshua muaj siv los ntawm nws tus kheej hauv cov khoom lag luam - nws yog ua tiav los ntawm pearls, rubies, emeralds thiab pob zeb diamond. Alexandrite yog nyob rau sab saum toj tsib ntawm tus nqi, nrog rau cov khoom siv kim xws li sapphire, pob zeb diamond, ruby thiab emerald.
Cov khoom siv lub pov haum feem ntau yog ua los ntawm kub, tab sis nyiaj kuj siv rau lub hom phiaj no.
Alexandrite tuaj yeem yuav ntawm tus nqi ntawm tsib puas duas las (artificial), thiab ntuj Ural - los ntawm tsib txhiab. Tus nqi siab tshaj plaws yog nees nkaum txhiab daus las ib carat.
Yam uas txiav txim siab tus nqi yog raws li hauv qab no:
- saturation ntawm cov ntxhia nrog cov xim tsis hais lub sijhawm ntawm hnub;
- muaj kev suav nrog thiab turbidity.
Cov neeg yuav khoom nruab nrab tuaj yeem yuav cov pob zeb hluavtaws uas zoo li tsis muaj qhov txawv ntawmqub. Nyob rau hauv Russia, lawv tsim ib qho analogue ntawm alexandrite, uas muaj ib tug lilac xim, zoo ib yam li amethyst.
Yuav ua li cas paub qhov analogue
Ib qho tshwj xeeb ntawm nuggets yog qhov hloov xim thaum lub teeb pom kev hloov pauv, uas yog tshwm sim los ntawm qhov muaj peb lub qhov muag pom hauv lub nugget. Interestingly, nyob rau hauv lub teeb fluorescent, cov nyhuv no yuav luag tsis pom.
Cov pob zeb tsuas zoo li Ural alexandrite yog ntsuab andalusite. Tab sis nws tsuas yog tsawg npaum li tus thawj.
Ntau zaus, raws li kev hloov pauv rau lub pov haum, cov khoom siv sib xyaw ua ke yog siv - spinel thiab corundum, zoo ib yam li thawj hauv tshuaj muaj pes tsawg leeg. Koj tuaj yeem paub qhov txawv ntawm lawv cov xim - tsis zoo li cov nugget, lawv shimmer los ntawm xiav-grey mus rau liab dawb thiab muaj zog ntau dua.
Cov neeg sib tw tseem ceeb rau kev hloov alexandrite yog cov khoom siv chrysoberyl, phenakite, cubic zirconia, inamori, garnet, andalusite, spinel. Thaum yuav ib daim ntawm cov hniav nyiaj hniav kub, koj yuav tsum xyuas seb puas muaj ib qho kev kuaj gemological.
Txawm hais tias tag nrho cov lus qhia, nws yog qhov nyuaj heev rau ib tus neeg zoo tib yam, tab sis tsis yooj yim sua kom paub qhov txawv ntawm qhov qub los ntawm analogue ntawm lawv tus kheej. Qhov kev xaiv zoo tshaj plaws yog hu rau tus kws tshaj lij jeweler - nrog kev pab los ntawm cov cuab yeej tshwj xeeb (spectroscope thiab refractometer), nws yuav txiav txim siab lub hauv paus chiv keeb ntawm cov ntxhia.
