Thiab nws cov muaju yog feem ntau prismatic. Kev txiav tawm los ntawm pyramidal thiab lwm yam ntsej muag. Nws yog cov ntxhia pob zeb nyuaj, Mohs hardness ntawm 8. Nws yog qhov nyuaj ntawm ib qho silicate ntxhia. Qhov no hardness ua ke nrog nws ib txwm pom thiab ntau yam xim txhais tau tias nws tau nrhiav kev siv dav hauv cov hniav nyiaj hniav kub. Tsis tas li raws li txiav gemstone. Xws li ntxiv rau intaglios. Thiab lwm yam gemstone carvings.
