Its deep blue to violet hues, often streaked with lighter shades, form fibrous or columnar patterns that shimmer in the light. Traditionally, dumortierite was valued for its protective qualities and believed to inspire patience and discipline. Metaphysically, it is thought to enhance mental clarity, focus, and organisation, helping one overcome stress and stay grounded. A captivating stone for collectors and spiritual enthusiasts alike.
