Ikariso ya Quartz muri rusange yerekeza kuri minerval quartz. Kirisiti ya Quartz ije muburyo butandukanye, harimo imitsi ya quartz, umucanga wa quartz, na quartzite, kandi nibintu byingenzi bigize ububumbyi bwa buri munsi. Quartz ni minerval ikwirakwizwa cyane kwisi, kandi uburyo bwayo butandukanye bugira uruhare runini mubigize ibikoresho byubutaka bwa buri munsi.
Quartz isangiye isano ryimbitse n'umucanga usanzwe hamwe na kirisiti; byose bikomoka kubintu bimwe - dioxyde ya silicon. Quartz, nka kristu na agate, ni ubwoko bwa dioxyde de silicon, ariko imyunyu ngugu itandukanye ikorwa muburyo butandukanye bwo gutegera. Iyo dioxyde ya silicon ihagaze neza, ikora kristu. Niba dioxyde ya silicon ihura na dehidrasi, ihinduka agate. Iyo hydrous silica colloids ikomera, opal irashingwa. Byongeye kandi, iyo ibinyampeke bya dioxyde de silicon iba ntoya kuruta microne nkeya, itandukaniro nka chalcedony, flint, na quartzite ya kabiri irashobora gukora.
