Tourmaline yog lub npe dav dav ntawm cov pob zeb tourmaline pawg. Nws cov tshuaj lom neeg muaj pes tsawg leeg yog qhov nyuaj heev. Nws yog ib lub nplhaib qauv silicate mineral uas muaj boron uas muaj txhuas, sodium, hlau, magnesium thiab lithium. [1] Qhov nyuaj ntawm tourmaline feem ntau yog 7-7.5, thiab nws qhov ceev yog txawv me ntsis nrog ntau hom. Saib lub rooj hauv qab no kom paub meej ntxiv. Tourmaline kuj tseem hu ua tourmaline, tourmaline, thiab lwm yam.
Tourmaline muaj cov yam ntxwv tshwj xeeb xws li piezoelectricity, pyroelectricity, far-infrared radiation thiab negative ion release. Nws tuaj yeem sib xyaw nrog lwm cov ntaub ntawv los ntawm kev siv lub cev lossis tshuaj lom neeg los tsim ntau yam khoom siv, uas siv rau hauv kev tiv thaiv ib puag ncig, hluav taws xob, tshuaj, kev lag luam tshuaj lom neeg, kev lag luam teeb pom kev zoo, cov ntaub ntawv tsim kho thiab lwm yam.
