Purpurite is a manganese phosphate mineral, ranging in color from violet to dark red, known for its intense purple hue. Despite its name (from the Latin word for purple), it is a brittle mineral and is not considered a gemstone, although it is sometimes used in jewelry and gem therapy due to its purported energetic properties. It is chemically classified as a manganese phosphate with the formula Mn₃PO₄ and may sometimes contain traces of iron.
