This 1982 issue from Nouvelle‑Calédonie et Dépendances features a vivid depiction of chalcanthite, a striking blue copper sulfate mineral known for its intense colour and well‑formed crystals. The stamp highlights a specimen from Ouegoa, a locality in the north of New Caledonia, reflecting the territory’s broader geological richness. As a mineralogical subject, chalcanthite is significant both scientifically and visually, making this issue a strong thematic fit for a mineral‑focused philatelic collection.
