About TazheraniteHide

Ideal formula ZrO2, same as cubic zirconia.
Bright orange to red-orange
Crystal System:
Named after its discovery locality, Tazheran (Tazheranskii) alkaline complex, Baikal Alkaline Province, Russia.
Compare also baddeleyite.
According to initial description Ti in Tazheranite is trivalent in difference from Zirkelite.

Possibly the natural form of 'cubic zirconia', although usually greatly impure compared to the synthetic gemstone.

A mineral with the name 'arkelite' was reported as isometric ZrO2 inclusions in zircon crystals. This is now regarded as synonymous with Tazheranite (Burke, 1989)

Classification of TazheraniteHide

Approval Year:

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
D : Metal: Oxygen = 1:2 and similar
L : With large (+- medium-sized) cations; fluorite-type structures

4 : AX2

7 : Oxides and Hydroxides
10 : Oxides of Zr and Th

Physical Properties of TazheraniteHide
