Aragonite crystals from Morocco. 10 - 30 grams. Sold per piece
Aragonite is a stunning carbonate mineral, one of the three most common natural crystal forms of calcium carbonate (CaCO3), alongside calcite and vaterite. Formed through biological and physical processes, it is often found in marine and freshwater environments. Aragonite features a unique crystal lattice structure, differing from that of calcite, and is known for its distinctive orthorhombic crystal system with acicular shapes. Sometimes, it forms pseudo-hexagonal structures due to repeated twinning. You can find aragonite in various forms, from columnar or fibrous to the fascinating flos-ferri (flowers of iron) formations, especially in areas like the Carinthian iron mines. A true natural wonder for any collector
