Blue Kyanite derives from the Greek word kyanos meaning deep blue (it is less often found in black, green or orange). It occurs in high pressure rocks formed during continental collisions, so typically found in mountain ranges. Helps one to speak truth and communicate clearly, helpful in meditation, developing intuition, lucid dreaming and creative pursuits. As an aid in detecting sincerity and truth, it can be useful in legal affairs. Kyanite is aligned with the throat so used as an aid in public speaking, singing and performing. Also excellent for logical thinking, mathematics and learning.
