Tistarite is an exceedingly rare mineral with the formula Ti₂O₃, thus being the natural analogue of titanium(III) oxide.^[2]^[1] In terms of chemistry it is the titanium-analogue of hematite, corundum, eskolaite, and karelianite. Other minerals with the general formula A₂O₃ are arsenolite, avicennite, claudetite, bismite, bixbyite, kangite, , yttriaite-(Y) and valentinite. Tistarite and grossmanite - both found in the famous Allende meteorite (so is kangite) - are the only currently known minerals with trivalent titanium. Titanium in minerals is almost exclusively tetravalent.^[1]^[3]^[4] The only known terrestrial occurrence of tistarite was found during minerals exploration by in the upper mantle beneath Mount Carmel, Israel.^[5]^[6]
