Nontronite is a unique clay mineral from the smectite group, which also includes well-known minerals like montmorillonite and saponite. Named after the picturesque town of Nontron in France, where it was first identified, this mineral is commonly found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash. Its captivating green color, ranging from soft pale shades to deep, rich greens, varies with iron content, making it a truly striking addition to any mineral collection.
