​Blue Kyanite Raw Crystal – Natural Blade Specimen

Kyanite is a striking silicate mineral famous for its vibrant blue, blade-like crystals and a unique property called anisotropic hardness, meaning it is much harder across its width than along its length. It is a high-pressure metamorphic rock primarily found in places like Brazil and the Appalachian Mountains.
​Primary Uses
​Industrial Refractories: Its extreme heat resistance makes it a key ingredient in kiln linings, furnace bricks, and high-temperature mortars.
​Ceramics: It is used to manufacture spark plugs, porcelain dinnerware, and bathroom fixtures because it expands when heated to offset shrinkage.
​Jewelry: Transparent, high-quality specimens are faceted into gemstones or cut into cabochons for rings and pendants.
​Metaphysical: Many believe it is a "stone of alignment" that enhances communication and doesn't retain negative energy—essentially the IT support of the crystal world.
