Kyanite is an absorbing crystal, which can absorb and condense some energy. According to legend, kyanite is an excellent harmony stone, meditation stone, gentle and powerful conductor, amplifier of high-frequency energy, and stimulator of supernatural ability and intuition. For Sagittarius people, being too impetuous is their death point, and weak willpower is Sagittarius's natural weakness. Kyanite, as the lucky stone of Sagittarius, can help coordinate its own temperament and make Sagittarius more calm and sophisticated. So Sagittarius and kyanite are a natural couple.
