Pseudomalachite is a copper phosphate mineral that often forms botryoidal to tabular or acicular aggregates with a green to olive-green color. It typically displays a adamantine to sub-metallic lustre and a vitreous sheen on fresh surfaces, with a compact, sometimes radiating habit that can resemble malachite in color but differs in composition and crystal structure. Crystals, when seen, are usually small and prismatic or tabular, sometimes forming intergrown masses that show a subtle, silky sheen under light.

About Pseudomalachite
Notable specimen sources include Germany and Slovakia, where high-quality crystals and dense aggregates have long been collected. Other productive localities include Portugal, the DR Congo, and the USA, yielding specimens that highlight the mineral’s range of green hues and metallic luster. Collectors value pseudomalachite for its geometric forms, crisp edges, and the way it contrasts with host minerals such as limescale or copper carbonates in matrix. Its relatively simple composition belies the visual appeal of well-formed specimens, which can display a striking contrast between fresh green surfaces and weathered, duller patinas.
