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 zaub mov

Cov zaub mov muaj ntau lub cev nqaij daim tawv. Lawv piav qhia txog ntawm lawv txoj kev ua tshuaj thiab sib xyaw. Cov cwj pwm txawv xws li kev siv dag siv thiab kev coj cwj pwm, kev ua kom muaj zog, cov lus sib dhos, kab xev, kev muaj zog, kev sib tw, kev tawg, kev sib cais, kev nqhis, kev tu los sis hnov ​​tsw,

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.

Synthetic gems muaj ntau lub cev, optically thiab sib puab zoo tib yam rau lub pob zeb ntuj, tab sis ua nyob rau hauv ib lub koom xwm. Hauv kev lag luam tawm, gemstones cov tswv lag luam siv feem ntau lub npe "lab uas tsim". Nws ua rau lub pob zeb hluavtaws ntau dua li "Hoobkas tsim".

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

Pob zeb diamonds

Piv txwv ntawm Artificial pob zeb muaj cubic zirconia, muaj li ntawm zirconium oxide thiab simulated moissanite, uas yog ob qho tib si gemstones simulants. Cov txuj ci ua tib zoo saib thiab xim ntawm lub pob zeb tiag tiag, tiam sis tsis muaj lawv cov chemical tsis yog lub cev. Moissanite ua tau muaj kev txhim kho siab tshaj dua pob zeb diamond thiab thaum pom ntawm ib qho ntawm qhov sib npaug thiab txiav pob zeb diamond yuav muaj ntau tshaj "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
