Actinolute (commonly associated with actinolite) is a metamorphic mineral formed within schists and amphibolites, created as heat and pressure transform earlier rocks. Typically green to dark emerald, it appears as silky, fibrous crystals or smooth polished stones with a natural sheen. In folklore, it was carried for courage and protection during travel. Metaphysically, actinolute is believed to strengthen inner calm, promote emotional resilience, and support grounded decision-making. Its soothing colour and earthy origins make it a reassuring stone for balance and steady energy.
