Edingtonite

Edingtonite is a white, gray, brown, colorless, pink or yellow zeolite mineral. Its chemical formula is BaAl₂Si₃O₁₀·4H₂O. It has varieties with tetragonal, orthorhombic or triclinic crystals.

Whilst some claim it was named after Scottish mineral collector James Edington (1787–1844), most sources (including the knowledgable mineralogist Haidinger) credit Thomas Edington FRSE (1814-1859), a Scottish geologist and mineralogist of greater fame.
