CVD shaybaar koray dheeman cabbirka
Karaatku waa halbeegga miisaanka dheemanka.Carat waxaa badanaa lagu wareersan yahay cabbirka inkastoo ay dhab ahaantii tahay cabbirka miisaanka.1 carat wuxuu u dhigmaa 200 milligram ama 0.2 garaam.Miisaanka hoose wuxuu muujinayaa xiriirka cabbirka caadiga ah ee u dhexeeya dheeman ee kordhinta miisaanka carat.Xusuusnow in kasta oo cabbirrada hoose ay yihiin kuwo caadi ah, shaybaar kasta oo CVD ah oo dheeman koray uu yahay mid gaar ah.
Midabka: DEF
Midabku waa midabka dabiiciga ah ee lagu arki karo shaybaarka CVD ee dheeman koray mana isbeddelo waqti ka dib.Dheemanka koray ee CVD-da aan midab lahayn ayaa u oggolaanaya iftiin badan inuu dhex maro dheeman midab leh, oo sii daaya dhalaal badan iyo dab.Isagoo u dhaqmaya sidii prism, dheemanku wuxuu iftiinka u kala qaybiyaa midabyo kala duwan wuxuuna ka tarjumayaa iftiinkan sida nalal midab leh oo loo yaqaan dab.
Caddayn: VVS-VS
Shaybaarka CVD ee koray dheemanka cad cad ayaa loola jeedaa joogitaanka wasakhda gudaha iyo gudaha dhagaxa.Marka dhagax qallafsan laga soo saaro kaarboonka hoose ee dhulka hoostiisa, raadadka yaryar ee walxaha dabiiciga ah ayaa had iyo jeer ku xayiran gudaha waxaana loo yaqaannaa ka mid noqoshada.
Gooyo: EXCELLENT
Goynta waxaa loola jeedaa xaglaha iyo saamiga dheeman.Goynta dheeman - qaabkeeda iyo dhamaystirkeeda, qoto dheer iyo ballaceeda, isku midka ah ee wejiyada - ayaa go'aamiya quruxdeeda.Xirfadda dheemanka lagu gooyo ayaa go'aamisa sida wanaagsan ee uu u iftiimayo iyo sida uu u leexiyo iftiinka.
