The chemical formula of mineral Moctezumite is indicated by Pb(UO2)(TeO3)2 or Lead Uranyl Tellurite. Moctezumite is actually a Sulfate mineral. This Moctezumite is most commonly used as mineral specimen and it is usually found exhibiting wonderful images when viewed closely under petrographic polarizing microscope used in the field of optical mineralogy. Moctezumite is a very rare tellurium mineral that was discovered by Richard Gaines (1917-1999), an American mineralogist, in the year 1965. The mineral was named aptly to its type of locality at Moctezuma Mine, Moctezuma, Sonora, Mexico. Mineral Moctezumite is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three axes of unequal lengths. Two of which are usually found in a position that is oblique or not perpendicular to one another. However, both of which are commonly found perpendicular to the third axis.

            Mineral Moctezuma is most commonly found showing orange to brownish orange color that could appear more fascinatingly interesting when viewed with the aid of polarized light microscope used in the field of optical mineralogy. Mineral Moctezuma is most commonly found exhibiting vitreous to adamantine luster when specimen is viewed in reflected light of petrographic polarizing light microscope for mineralogists. Most crystals of Moctezumite are found translucent in appearance. The crystal habit of mineral Moctezumite as described in the field of optical mineralogy includes small granular crystals. Mineral Moctezumite is most commonly found exhibiting good cleavage in one direction that can be seen more clearly exhibited when specimen is viewed closely with the aid of petrographic polarizing light used in the field of optical mineralogy. The hardness measure of mineral Moctezumite when it is evaluated using the Mohs scale method is 3. Moctezumite is most commonly found leaving a pale orange streak when specimen is rubbed on a white porcelain streak plate. The specific gravity measure of the mineral Moctezumite is most commonly found approximately 5.7 grams per cubic centimeters, which is considered very heavy for translucent minerals.

Moctezumite is a radioactive mineral and should be stored away from minerals that are affected by radioactivity and of course human exposure should be limited. The index of refraction of mineral Moctezumite is usually found very high at 2.11 t 2.12 when specimen is evaluated under polarizing microscope used in optical mineralogy. Mineral Moctezumite is most commonly found associated with other interesting tellurium minerals, tellurates, and tellurites. The best field indicators of mineral Moctezumite include high density, locality, radioactivity, color, and cleavage. Mineral Moctezumite has limited occurrence at its type of locality at Moctezuma Mine, Moctezuma, Sonora, Mexico.
