'''Davisite''' is an exceedingly rare mineral of the pyroxene group, with formula CaScAlSiO<sub>6</sub>. It is the [scandium](/source/scandium)-dominant member.<ref>Ma, C., and Rossmann, G.R., 2009: Davisite, CaScAlSiO<sub>6</sub>, a new pyroxene from the Allende meteorite</ref><ref name=Mindat>Mindat, http://www.mindat.org/min-38829.html</ref> It stands for [scandium](/source/scandium)-analogue of other pyroxene-group members, [esseneite](/source/esseneite), [grossmanite](/source/grossmanite) and [kushiroite](/source/kushiroite).<ref name=Mindat /> Davisite is one of scarce minerals containing essential scandium.<ref>[http://www.mindat.org/element/Scandium Scandium, The mineralogy of Scandium - Mindat. org]</ref>

It is named for [Andrew M. Davis](/source/Andrew_M._Davis), an American meteoriticist and professor of astronomy and geoscience at the University of Chicago.

Based on a synthesized sample, the mineral likely crystallizes in the [monoclinic crystal system](/source/monoclinic_crystal_system) with space group ''C2/c''.<ref>{{cite journal |last1=Ohashi |first1=H. |last2=Ii |first2=N. |journal=Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists |volume=73 |year=1978 |pages=267–273 |title=Structure of calcium scandium aluminum silicate (CaScAlSiO6)-pyroxene|doi=10.2465/ganko1941.73.267 |doi-access=free }}</ref>
