This mineral was named after French geologist Cordier. The name iolite comes from ios, the Greek word for violet. Iolite is commonly known as "water sapphire" in its deep blue sapphire color. As an indigo stone it can aid in increasing your cosmic vision and purpose in life.
Iolite has been used by shamans to enhance their ability to have clear visions. Other metaphysical beliefs hold that iolite promotes pure thoughts, intuition and self-acceptance.
