Tyuyamunite is a uranyl vanadate mineral with a distinctive orange-yellow hue and a glassy to resinous luster. It commonly forms blocky to tabular crystals and radiates in prismatic groups, sometimes displaying radiant or cluster habits that catch the light. The mineral’s formula reflects its composition of calcium, uranium, vanadium, and water, with variable hydration that can affect color and cleaving tendencies.

About Tyuyamunite
Notable specimens have come from classic uranium-rich localities around the world, including mines in the United States and Mexico, with other important occurrences across Africa and Asia. Collectors prize Tyuyamunite for its lively color, sharp crystal faces, and relatively bright fluorescence under ultraviolet light, when present. Specimens from well-known deposits often display complementary minerals such as carnotite or uraninite in the same pocket, adding context to the association and helping tell a complete paragenesis.
For mineral enthusiasts, Tyuyamunite offers both aesthetic appeal and scientific interest, illustrating uranyl oxide and vanadate chemistry in a compact, colorful form. Its occurrence in well-documented localities provides tangible connections to uraniferous geology and hydrothermal processes, rewarding careful handling and preservation of delicate hydration-dependent forms.
