Artinite is a hydrated carbonate mineral with the formula Mg2(CO3)(OH)2·3H2O. It forms as a secondary mineral in carbonate rocks and near alteration zones, typically presenting as colorless to pale green crystals that can display a soft, vitreous to pearly lustre. The habit is usually tabular or platy, sometimes forming delicate aggregates, and its translucent to transparent appearance adds to its subtle beauty.

About Artinite
Significant specimens have been reported from the United States, among other localities, where artinite associates with other magnesium-rich carbonates and hydroxy minerals. The mineral is prized for its rarity and its ability to form in specific alteration environments, making well-crystallized pieces desirable to collectors who seek minerals with a combination of rarity, elegance, and mineralogical interest. Collectors often value artinite for the challenge of locating pristine crystals and for its understated, sculptural appeal among carbonate minerals.
