Matombo anokosha chaizvo anogona kutora mweya wedu patinovaona. Ndiani asina kumboona dhayamondi kana ringi yesafiri akashevedzera pamusoro payo? Runako rwavo chete ndirwo runoita kuti vakoshe zvakadaro? Nei zvimwe zvichikosha kwatiri?
Most magemstone ari zvicherwa zvinoitika zvakasikwa muvhu. Chakajairika ndechekuti Goldstone, iyo inogadzirwa nesilicon uye oxygen, maviri emakemikari akajairika kana zvinhu pasi. Kunyangwe vanhu vazhinji vasingawani zvakadaro makristasi kunze kwekunge uchitsvaga zvakanyanya, zvichiri zvakajairika mugem renyika.
Humwe hunhu hunogadza kukosha kwegemari kushomeka kwahwo. Dhaimondi, tenda mazviri kana kwete, ndiro dombo rakajairika. Zvisinei, kutengesa uye kugoverwa kwemadhaimani zvakanyatso kudzorwa, izvo zvinoita kuti kudiwa kwemadhaimani kwese hunhu kuve kwakakosha kwazvo. Zvirokwazvo yakakwana, isina chainopomerwa diamond hazviwanzo kuitika, asi madhaimani pachawo haana kunyanya kushomeka.
Mamwe mabwe anokosha anowanikwa zvakanyanya, sapphires uye korari, ayo ari chikamu chemhuri yebheriri yezvicherwa. korari zvakajairika kupfuura nesafiri uye yepamusoro mhando mavara mune ese ari maviri asingawanzoitika.
Mucherwa unonzi benitoite unongowanikwa chete mumupata weSan Benito muCalifornia, uko kunongova nemazana carat ayo anowanikwa gore rega rega. Inyika gem reCalifornia uye ine hexagonal-yakaita sekristaro. Inogona kutemwa uye kukwenenzverwa kuti ibudise masafire-ane mavara matombo anokosha.
Mamwe matombo anotoshamisa kupfuura bentitoite. Ivo vashoma kwazvo, zvekuti matatu kana mana chete acho aripo munyika. Uye iyo nzvimbo iyo dombo rakawanikwa inogona kuita mutsauko mukuru zvakare. Nepo peridot iri gem rakajairika, pakanga paine chaiwo makarati eperidot akawanikwa mune meteorite, ichiita iro rimwe rematombo asinganetsi zvachose!
