Ces muaj ib tug lo lus nug txog lub tseem rau qee kom sib kub. Nws yog ntseeg hais tias tsuas dawb-rimmed pob zeb diamond yog tau mus pib ua si nyob puv lub zog. Nyob rau hauv tas li ntawd, ib daim ntawm hniav nyiaj hniav kub yog lub zoo meej kho kom zoo nkauj rau tej pab tub rog, tab sis, yog hais tias lub pob zeb yuav puag ncig lub dawb kub, muaj pes tsawg leeg uas tas yuav nrhiav tau tawm.

Yuav ua li cas cov neeg siv rau qee kom sib tus precious hlau? Chiv nws yog nyiaj, npib tsib xee tau ces siv additives, zinc thiab tooj liab.

Nws yog txuas mus rau cov tsis muaj nyob rau hauv lub khw muag khoom ntawm hniav nyiaj hniav kub, nyob qhov twg lub ntug ntawm lub pob zeb tau txais kev pab raws li ib tug noble dawb kub, ib tug hlau muaj pes tsawg leeg uas yuav tsum tau muaj yam tsawg kaum yim feem pua platinum los yog palladium. Tus nqi ntawm tej khoom loj hlob ho, uas ua rau zus tau tej cov unprofitable hniav nyiaj hniav kub. Tsuav txhob yog cov kom cov khoom ua rau txim.

Ib tug qauv ntawm cov dawb kub nyob rau hauv lub feem pua ntawm cov kub thiab ligatures. Ib gram ntawm cov qauv hlau 375, e.g., muaj tsuas 37.5 feem pua kub nws tus kheej, tag nrho lwm yam - tshuaj. Ntawm cov hoob kawm, tus nqi ntawm tej khoom yuav tsis muaj, thiab hniav nyiaj hniav kub, nws yuav tsis muab suav hais tias. Qhov no yog cia li hniav nyiaj hniav kub, tarnishes nyob rau hauv cov huab cua.

Platinum thiab palladium dawb kub qiv ib tug noble ntxoov ntxoo, thiab lwm yam impurities, raws li hais saum toj no, ua rau nws dimmer.
