Olivenite is a copper arsenate mineral that forms as green to olive-brown, often vitreous to pearly crystals. It typically occurs as prismatic, elongated crystals or radiating clusters and can display a resinous to sub-metallic luster. The mineral commonly appears in hanging or fibrous aggregates within fissures of copper-bearing rocks, frequently alongside secondary copper minerals that form in oxidative zones.

Notable specimens have come from several classic localities globally, including arid or desert regions where secondary arsenates develop in oxide-rich environments. Namibia, the United Kingdom, the United States, Mexico, and Greece are among the places known for well-crystallized Olivenite and associated assemblages, sometimes yielding eye-catching, saturated color and crisp crystal form. Collectors prize Olivenite for its rich color range, striking termination shapes, and its historical association with copper deposits observed in old mines and secondary mineral parageneses.
