One-of-a-kind natural kyanite. You will receive a piece similar to those shown. Size: 5 to 6 inches (sizes vary) Kyanite is an aluminum silicate mineral commonly found in metamorphic rocks formed under high pressure conditions. It develops during regional metamorphism where clay-rich sediments are transformed by heat and pressure. Its color is typically blue due to trace amounts of iron and titanium within the crystal structure. These specimens usually display elongated, blade-like crystals with a fibrous or striated texture, often mounted on a metal stand to highlight the natural formation. Each item is unique in shape, color, and pattern. Higher-grade pieces are selected first. Photos represent overall quality and appearance.
