The chemical formula of mineral Zuenerite is indicated by the formula Cu(UO2)2(AsO4)2 – 10-16H2O or Hydrated Copper Uranyl Arsenate. Zuenerite is actually a Phosphate mineral. It is considered as a minor ore of Uranium and it is also considered as mineral specimen. Zuenerite was named after G.A. Zuener, a German physicist. The pseudocubic crystals of Zuenerite can be quite attractive most especially when viewed under polarizing microscopes used in optical mineralogy. Zuenerite is a radioactive mineral. Thus, it should be stored away form other minerals that are easily affected by radioactivity. Human exposure should be also limited.

             Zuenerite is most commonly found showing interesting color that varies from the typical emerald green to yellow that can be more splendidly exhibited under polarizing microscope used in optical mineralogy. Zuenerite is most commonly found showing vitreous, pearly luster on cleavage surfaces when viewed in reflected light of polarizing microscope for mineralogists. Most crystals of mineral Zuenerite can be found transparent to translucent in appearance. Zuenerite is known to crystallize in the tetragonal system of crystal formation. In optical mineralogy, this tetragonal system comprises crystals having three axes, which are all in a position perpendicular to one another. Two axes are usually found having the same or equal length. The crystal habit of mineral Zuenerite as described in the field of optical mineralogy usually include tabular square crystals dominated by two pinacoid faces. Bipyramidal crystals are also seen. Crystals can actually look cubic or pseudocubic too. Zuenerite can be also found as crusts, micaceous, foliated and earthy.             Zuenerite is most commonly found showing perfect basal cleavage found in one direction when evaluated with the aid of petrographic polarizing microscope used in optical mineralogy. It is also most commonly found showing uneven fracture under polarized microscope for mineralogists. The hardness measure of the mineral when it is evaluated using the Mohs scale method is usually ranging from 2 to 2.5. The specific gravity measure of the mineral is approximately 3.2 to 3.4 grams per cubic centimeters, which is slightly above average for translucent minerals. Zuenerite is most commonly found leaving a pale green streak when rubbed on a white porcelain streak plate. Zuenerite is found radioactive, non-fluorescent and its cleavage sheets are not bendable but are in fact brittle.  Zuenerite is most commonly found associated with other interesting minerals including barite, fluorite, Scorodite, Olivenite, moxite, Uraninite, brochantite, Walpurgite and other uranium minerals. The best field indicators of mineral Zuenerite usually include color, non-fluorescence, crystal habit, radioactivity, associations especially with arsenic minerals and brittle cleavage sheets. Zuenerite notably occurs at several localities including Germany, England, some areas in USA and other localities with uranium arsenic minerals.
