Iolite is normally violet-blue in color, albeit, a sometimes dull blue. The best quality faceted gems can sometimes resemble tanzanite or sapphires. Prior to the 1980s, it was not readily available, but supply has increased, making it a beautiful addition to most jewelry.
Its name is derived from the Greek word for violet. Sometimes misleadingly called a "Water Sapphire" because it looks clear and watery from the side, but can resemble a sapphire when looking at it head on
