Kyanite

This attractive blue mineral often appears as large, well-formed bladed crystals, making it a popular material for gemological collectors and jewelry makers alike. Kyanite has an almost fibrous appearance, especially as stones are often left rough to prevent stone loss during polishing. Kyanite is strongly believed to facilitate meditation; some practitioners consider its meditative power to be one of its two defining features. The second is that they believe kyanite never needs to be cleansed of negative energies--because it cannot accumulate or retain them!
