Kev tsim cov zirconia gemstones los ntawm zirconia hmoov yog ib qho tseem ceeb ntawm zirconia txoj kev sib sib zog nqus ua thiab daim ntawv thov.Cov hluavtaws cubic zirconia yog ib qho nyuaj, tsis muaj xim, thiab optically flawless crystal.Vim tias nws tus nqi qis, ruaj khov, thiab zoo li cov pob zeb diamond, cubic zirconia gemstones tau hloov pauv tseem ceeb tshaj plaws rau pob zeb diamond txij li xyoo 1976.
