Comment: Eudialyte, whose name derives from the Greek eu and dialytos, meaning "well decomposable", is a somewhat rare, red silicate mineral, which forms in alkaline igneous rocks, such as nepheline syenites. Its name alludes to its ready solubility in acid. Eudialyte is used as a minor ore of zirconium. Another use of eudialyte is as a minor gemstone, but this use is limited by its rarity, which is compounded by its poor crystal habit. These factors make eudialyte of primary interest as a collector's mineral.

Minerals: Analcime (NaAlSi₂O₆ (H₂O)) Eudialyte (Na₄(Ca,Ce)₂(Fe⁺⁺,Mn,Y)ZrSi₈O₂₂(OH,Cl)₂ (?))
