Iolite
Violet-blue to denim blue, changing tone as the stone turns, Iolite carries a moody, refined, and subtly magical mood. Material is associated with India, Sri Lanka, Madagascar, and Tanzania; in crystal traditions it is linked with intuition, clarity, focus, and confidence.
Iolite can show different colors from different directions; that strong pleochroism is why it has long been nicknamed the “water sapphire.”
