Stilpnomelane is a rare phyllosilicate mineral typically found in low- to medium-grade metamorphic rocks such as schists and gneisses. It usually appears as dark brown to black metallic flakes or platy crystals with a submetallic to silky lustre, often forming layered, reflective aggregates. In folklore, Stilpnomelane symbolises resilience and grounding. Metaphysically, it is believed to enhance focus, clarity, and emotional stability. The stone is said to support meditation, spiritual insight, and personal growth, helping to harmonise energy and strengthen inner balance.
