Nontronite is a green clay mineral belonging to the smectite group, alongside montmorillonite and saponite. First discovered in the town of Nontron, France, this mineral is typically found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash deposits. Its vibrant green color, which ranges from pale to deep green depending on iron content, makes nontronite highly prized by collectors, geologists, and mineral enthusiasts worldwide.
