Kyanite Beads

Kyanite is a blue or light green mineral that can form in fibers, blades, and columns. It most commonly results from clay minerals that have undergone high-temperature and high-pressure metamorphism. In the science of petrology, kyanite is used as a metamorphic index mineral because it forms at such particular conditions. While kyanite can be found in many locations worldwide, it tends to grow in small crystals, making finding pieces suitable for cutting into gemstones a difficult task.
