Nontronite is a charming clay mineral that falls under the smectite group, which also includes familiar minerals like montmorillonite and saponite. It gets its name from the lovely town of Nontron in France, where it was first discovered. You'll often find nontronite in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash deposits. This mineral is especially loved for its beautiful green hue, which can range from a gentle pale green to a rich dark green, all depending on its iron content.
