Tourmaline kuj yog ib qho kev sib tw rau tus tswvcuab ntawm lub suab paj nruag uas muaj lub cev siv ua suab nrov. Nws tshwm sim ntev li, ntev rau cov pob txha loj thiab cov xim thwj cim uas yog feem ntau ntawm qhov sib npaug hauv seem, feem ntau nrog cov ntsej muag muag. Tsis tas li ntawd, lub hom phiaj ntawm kev tshem tawm ntawm qhov xaus ntawm cov nplais yog qee zaum asymmetrical, hu ua hemimorphism.

Txuas ntxiv, me me ntawm cov pob txha muaj prismatic muaj ntau nyob rau hauv cov nplua graine ntawm granite. Nws hu ua aplite, thiab nws yog feem ntau ua qauv radial daisy zoo li qauv. Tourmaline muaj peb sab prisms, tsis muaj lwm yam ntxhia muaj peb sab. Cov plaub hau feem ntau muaj cov ntsug hnyav ntsug uas ua rau muaj qhov sib npaug ntawm cov kab thev voos.

Thaum kawg, tourmaline tsis tshua zoo euhedral. Ib qho kev tshwj xeeb yog qhov zoo ntawm cov tourmalines ntawm Yinnietharra, hauv thaj Australia. Tag nrho cov hemimorphic muaju yog piezoelectric, thiab feem ntau pyroelectric thiab.

Lub precipitates uas ua rau sib tham hauv chrysoberyl yog cov pob zeb hauv av rutile, muaj li feem ntau ntawm titanium dioxide. Cov ntaub ntawv kuaj pom tau tsis muaj pov thawj ntawm cov hlab ntsha los yog cov fibers.The koob precipitates txhua align perpendicularly txoj cai rau miv lub qhov muag nyhuv. Lub lattice parameter ntawm koob yuav ntais tsuas yog ib qho ntawm peb txoj kab orthorhombic siv lead ua ntawm cov chrysoberyl, los ntawm kev sib haum xeeb raws li qhov kev taw qhia.
