Umbala oguqula iSapphire kwiCorundum iyinyani, iya kubonakala imibala eyahlukileyo ekukhanyeni okwahlukileyo, eyaziwa ngokuba ngumbala oguqula i-corundum okanye ubuncwane bombala, utshintsho lombala kulindeleke ukuba lubangelwe yinto ye-chrome kwi-corundum.
Iimpawu ezahlukileyo zendalo kunye ne-SyntheticIisafire eziluhlaza zisika iprotolith eluhlaza okwesibhakabhaka ukubonisa umbala ohlukeneyo oluhlaza okanye oluhlaza okwesibhakabhaka ngaphambili, emva koko iisafire eziluhlaza zendalo zinokuqulunqwa.
I-Orenji, i-streak ayinambala, i-transparent, i-glassy luster, ubulukhuni 9, ubunzima obuthile 4.016, {0001}, {10 ˉ 10} Cleavage.[1]
Isafire ebomvu ebomvu yesafire: ngaphambili, uluntu lwamazwe ngamazwe lukholelwa ukuba yi-corundum kuphela enobunzulu obuphakathi ukuya kumnyama obomvu okanye obomvu obomvu inokubizwa ngokuba yirubhi.Ezo zijike isibane esibomvu sibe kukhanya kakhulu zibizwa ngokuba yisafire epinki.
IGem ebotshelelwe zonke iintlobo zegem grade corundum ngaphaya kwerubhi zibizwa ngokuba yisafire.Igama leminerali yeSapphire ye-corundum, iqela leeminerali ze-corundum.
Isafire emthubi ikwabizwa ngokuba yitopazi kwishishini.Iintlobo ngeentlobo ze-corundum yegreyidi etyheli.Umbala usuka kutyheli okhanyayo ukuya kumthubi weCanary, umthubi obugolide, umthubi wobusi kunye nomdaka otyheli okhanyayo, kunye nomthubi wegolide ngowona ubalaseleyo.Umthubi ngokuqhelekileyo unxulunyaniswa nobukho be-iron oxide.
