Annabergite specimens for sale

Annabergite is a hydrated nickel arsenate mineral that forms translucent to emerald-green crystals and associated masses. It typically exhibits a vitreous to resinous lustre and can occur as prismatic or tabular crystals, sometimes with a pleasing, glassy surface that enhances color. The mineral often forms as secondary crusts or aggregates in oxidized nickel-rich environments, and it can occur alongside other nickel arsenates and secondary nickel minerals in sulfide-bearing or arsenate-bearing localities. Notable specimens have come from well-known deposits in Greece, Morocco, and the United States, with other established localities contributing rich, grassy-green crystals that attract display-focused collecting and study.
