I-Tourmaline ligama eliqhelekileyo leeminerali zeqela le-tourmaline. Ukwakheka kwayo kweekhemikhali kuyinkimbinkimbi. Yiminerali ye-silicate yesakhiwo sendandatho ebonakaliswa yi-boron equlethe i-aluminium, i-sodium, i-iron, i-magnesium kunye ne-lithium. [1] Ubunzima be-tourmaline buhlala buyi-7-7.5, kwaye ubuninzi bayo bahlukile kancinci kwiintlobo ezahlukeneyo. Jonga itheyibhile engezantsi ukuze ufumane iinkcukacha. I-Tourmaline ikwaziwa njenge-tourmaline, i-tourmaline, njl.njl.

I-Tourmaline ineempawu ezikhethekileyo ezifana ne-piezoelectricity, i-pyroelectricity, i-far-infrared radiation kunye ne-negative ion release. Ingadityaniswa nezinye izinto ngeendlela zomzimba okanye zeekhemikhali ukuvelisa iintlobo ngeentlobo zezinto ezisebenzayo, ezisetyenziswa kukhuseleko lokusingqongileyo, kwi-elektroniki, kumayeza, kushishino lweekhemikhali, kushishino lokukhanya, kwizixhobo zokwakha nakwezinye iindawo.

I-Tourmaline erhabaxa
Ikristale enye okanye ikristale encinci eyombiwa ngqo kwii-agglomerates zemigodi ibe ngumthamo othile we-tourmaline enkulu.
