Nontronite is a captivating clay mineral in the smectite group, alongside minerals like montmorillonite and saponite. Named after the charming town of Nontron in France, where it was first discovered, nontronite is commonly found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash layers. Its beautiful green coloration, ranging from soft pale green to deep rich green depending on iron content, makes nontronite highly prized by collectors, geologists, and mineral enthusiasts.
