General
Category	Inosilicate minerals (single chain)
Group	Pyroxene group, clinopyroxene subgroup
Formula	CaScAlSiO6

Davisite is an exceedingly rare mineral of the pyroxene group, with formula CaScAlSiO₆. It is the scandium-dominant member.¹² It stands for scandium-analogue of other pyroxene-group members, esseneite, grossmanite and kushiroite.² Davisite is one of scarce minerals containing essential scandium.³

It is named for 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 with space group C2/c.⁴
