Enchanting Kyanite: Find Your Life's Hidden Treasures Kyanite is a great stone that comes from the Greek word "kuanos," which means blue. It is an aluminum silicate mineral. Speaking of its namesake, the stone is primarily valued for its stunning blue hue, which can range from light to deep and is brought on by the iron and titanium components in the structure. However, because of its numerous gorgeous color formations—green, pink, white, black, gray, orange, and occasionally yellow—and brown, kyanite is a popular gem among aficionados or collectors.
