Cov zaub mov gemstones?

Ib pob zeb hauv av yog ib qho tsim muaj tshuaj lom neeg, feem ntau ntawm crystalline daim ntawv thiab tsis ua los ntawm lub neej muaj dab. Ib pob zeb hauv av muaj ib hom tshuaj muaj pes tsawg leeg, txawm yog lub pob zeb yuav ua rau cov khoom sib txawv me me. Cov kev kawm ntawm cov zaub mov muaj mineralogy.

Feem ntau cov gemstones yog cov ntxhia

Cov zaub mov muaj ntau lub cev. Lawv cov lus piav qhia depsnds ntawm lawv cov qauv thiab tshuaj lom neeg. Cov cwj pwm txawv uas suav nrog cov qauv siv lead ua thiab tus cwj pwm, kuj muaj qhov nyuaj, luster, diaphaneity, xim, streak, lub zog ntev, sib ntaus, pob txha tawg, feem, tshwj xeeb kev sib nqus, hlau nplaum, saj lossis hnov ​​tsw, radioactivity, thiab cov tshuaj tiv thaiv rau cov kua qaub.

Exemple ntawm pob zeb gemstones: Quartz, pob zeb diamond, corrundum, beryl, ...

Khoom cua gemstones

Nws yog ib qho tseem ceeb kom paub qhov txawv nruab nrab ntawm cov khoom cua lub cev, thiab imitation lossis simulated gems.

Cov hluavtaws hluavtaws yog lub cev, kev xaiv zoo thiab cov khoom siv zoo tib yam rau lub pob zeb ntuj, tab sis ua nyob rau hauv Lub Hoobkas. Hauv kev lag luam maket, lub khw muag khoom gemstones siv ntau lub npe "lab tsim". Nws ua rau cov pob zeb hluavtaws ua lag luam ntau dua li "lub Hoobkas tsim".

Exemple ntawm khoom cua gemstones: hluavtaws corrundum, hluavtaws pob zeb, hluavtaws quartz, ...

Khoom neeg tsim gemstones

Cov piv txwv ntawm Artificial pob zeb suav nrog nyhav zirconia, tsim ntawm zirconium oxide thiab simulated moissanite, uas yog ob qho tib si gemstones simulants. Cov qauv siv luam tawm qhov zoo thiab xim ntawm lub pob zeb tiag tiag tab sis muaj tsis yog lawv cov tshuaj lom neeg lossis cov yam ntxwv ntawm lub cev. Moissanite tiag tiag muaj qhov ntsuas siab dua zoo siab dua pob zeb diamond thiab thaum hais tawm ntawm ib sab sib luag thiab txiav pob zeb diamond yuav muaj ntau "hluav taws" tshaj lub pob zeb diamond.

Pob zeb

Pob zeb yog ib yam khoom ntuj tsim, ib qho khoom hnyav ntawm ib lossis ntau dua minerals lossis mineraloids. Piv txwv li, Lapis lazuli yog lub pob zeb loj xeb metamorphic. Nws kev faib tawm yog pob zeb zoo nkauj tshooj. Qhov tseem ceeb tshaj plaws ntawm cov pob zeb lapis yog lazurite (25% rau 40%), lub feldspathoid silicate ntxhia.

Organic gemstones

Muaj ntau hom khoom siv los siv ua gems, suav nrog:
Amber, Ammolite, Pob txha, Copal, Coral, Ivory, Dav hlau, Nacre, Operculum, Pearl, Petoskey pob zeb

Mineraloids

Lub mineraloid yog cov khoom ua ntxhiab tsw zoo li uas tsis ua rau crystallinity. Mineraloids muaj cov tshuaj sib xyaw tshuaj sib txawv uas txawv tshaj li cov feem ntau cov khoom noj uas tau txais rau cov zaub mov tshwj xeeb. Piv txwv, obsidian yog ib qho iav amorphous thiab tsis siv lead ua. Dav hlau yog muab los ntawm kev txiav ntoo hauv qab huab cua. Opal yog lwm qhov mineraloid vim nws tsis-crystalline xwm.

Cov txiv neej ua cov mineraloids

Txiv neej ua iav, yas, ...
