Amakristalu mahle, ayamangaza, futhi asesetshenziswe amakhulu eminyaka ngezakhiwo zawo nezinzuzo ezihlukahlukene. Kusukela ekuphulukisweni kwekristalu kuya ekuhlobiseni ngekristalu, lawa mamineral akhazimulayo anezinhlobonhlobo zokusetshenziswa futhi angaletha amandla amahle kanye nokuphulukiswa ezimpilweni zethu.
Amakristalu asesetshenziswe amakhulu eminyaka ngezindawo zawo zokuphulukisa ezahlukahlukene kanye nekhono lokuletha amandla amahle ezimpilweni zethu. Ukusuka ekudambiseni ingcindezi nokukhathazeka kuye ekukhuthazeni ukuzithanda nokuchichima, kukhona ikristalu yazo zonke izidingo.
Uma ungumuntu othanda amatshe ayigugu, cishe uke wezwa ngeso lehlosi. Kodwa bewazi yini ukuthi kunokwehluka okungajwayelekile kwaleli tshe eliyigugu eliphuzi ngombala? Laziwa njengehlo lehlosi eliphuzi, leli tshe eliyigugu lakhiwa ngenqubo ye-metamorphism futhi lakhiwe nge-quartz. Kulokhu okuthunyelwe kwebhulogi, sizongena ku-geology yehlo lengwe eliphuzi futhi sifunde ngendlela elakheka ngayo nokuthi lingatholakala kuphi.
