Zeunerite is a hydrated uranyl phosphate-sulfate mineral with copper in its formula, commonly forming slender, elongated crystals and tabular aggregates. It typically displays a green to olive-green hue and a vitreous to submetallic luster, often occurring as prismatic or acicular crystals that can form well-terminated, radiating clusters. The mineral’s habit and color make it instantly recognizable among uranium-bearing secondary phosphates, and its crystals sometimes fluoresce under ultraviolet light. Notable localities have yielded specimens with rich, lustrous prisms that enhance the mineral’s appeal to collectors seeking mineralogical specimens from diverse environments.

About Zeunerite
Collectors prize zeunerite for its distinctive color, crystal form, and association with uranium-bearing assemblages. It often occurs in oxidized zones of uranium-rich ore deposits and in alteration zones where phosphate minerals crystallize from metasomatic fluids. Specimens from classic European and American localities, alongside notable finds from Brazil and Mexico, demonstrate Zeunerite’s regional diversity. High-quality crystals can be aesthetically striking when mounted or stored with proper care to preserve their delicate, often layered, termination and overall integrity.
