'''Fabianite''' is a [borate mineral](/source/borate_mineral) with the [chemical formula](/source/chemical_formula) CaB<sub>3</sub>O<sub>5</sub>(OH). It is colorless and leaves a white streak. Its crystals are [monoclinic](/source/monoclinic) [prismatic](/source/prism_(geometry)). It is transparent and [fluorescent](/source/fluorescent). It has vitreous luster. It is not [radioactive](/source/radioactive). Fabianite is rated 6 on the [Mohs Scale](/source/Mohs_Scale). It was named for [Hans-Joachim Fabian](/source/Hans-Joachim_Fabian), a German geologist.
