Kyanites are usually rather opaque and too buried in chunks of quartz matrix to be all that attractive, but once in awhile you get dazzling specimens such as this with intense blue color, and translucent, that have been excavated or grown in pockets so that the crystals are shown off on a perfect natural "base" of quartz, as with this specimen. The larger crystal measures 9.5 cm. It forms a beautiful arrangement with the smaller crystals and contrasting white quartz. The terminations of kyanite crystals are so naturally rough that it is often hard to tell whether the crystals are terminated or not.
