Etymology

Mandarinoite is named after Joseph A. Mandarino, a mineralogist recognized for his contributions to mineral classification and nomenclature. The mineral was officially approved by the International Mineralogical Association (IMA).

How to recognize it

Mandarinoite can be identified by its low hardness, typically below 3 on the Mohs scale, and its pale yellow to brownish color. It has a low density and a vitreous to dull luster. The streak is likely white or pale yellow. Due to its rarity and softness, it is not commonly confused with other minerals, though its color and luster may resemble those of other hydrated sulfates or selenites.
