Carnallite is a hydrated potassium magnesium chloride mineral that forms in evaporite deposits. It typically crystallizes as pinkish to colorless, tabular to prismatic crystals with a vitreous to slightly silky luster, often occurring in bright, well-formed aggregates. The mineral is commonly associated with other evaporite minerals such as sylvite and halite, and it can form alongside amply hydrated minerals in saline depositional environments.

About Carnallite
Notable specimens have been recovered from evaporite basins in Germany and the United States, where long-running mining and careful specimen collection have yielded well-formed crystals and rich crystal groups. Collectors prize Carnallite for its delicate appearance and its role in the history of evaporite mining, as well as for the curiosity of its hydrated structure, which can render clear, light-sensitive crystals that require careful storage. While not as ubiquitous as some other halides, when Carnallite crystallizes in pristine conditions it offers a distinctive, glassy sheen and a soft color palette that stands out among evaporite assemblages.
