I-Tourmaline igama elijwayelekile lamaminerali eqembu le-tourmaline.Ukwakheka kwayo kwamakhemikhali kuyinkimbinkimbi.Isakhiwo sendandatho ye-silicate mineral ebonakala nge-boron equkethe i-aluminium, i-sodium, insimbi, i-magnesium ne-lithium.[1] Ukuqina kwe-tourmaline kuvame ukuba ngu-7-7.5, futhi ukuminyana kwayo kuhluke kancane ngezinhlobo ezahlukene.Bheka ithebula elingezansi ukuze uthole imininingwane.I-Tourmaline yaziwa nangokuthi i-tourmaline, i-tourmaline, njll.

I-Tourmaline inezinto eziyingqayizivele ezifana ne-piezoelectricity, i-pyroelectricity, imisebe ye-infrared ekude kanye nokukhululwa kwe-ion engalungile.Ingahlanganiswa nezinye izinto ngezindlela ezingokwenyama noma zamakhemikhali ukukhiqiza izinto ezihlukahlukene zokusebenza, ezisetshenziselwa ukuvikelwa kwemvelo, i-electronics, imithi, imboni yamakhemikhali, imboni yokukhanya, izinto zokwakha kanye neminye imikhakha.

I-tourmaline inzima
Ikristalu eyodwa noma i-micro crystal embiwa ngokuqondile isuka emayini ihlanganisa ivolumu ethile ye-tourmaline enkulu.
