KYANITE GEMSTONE Characteristics and Properties
1. Color: Kyanite is most commonly found in shades of blue, ranging from pale to deep blue. However, it can also occur in other colors such as green, gray, black, and white. Some kyanite specimens may even display color zoning, with different hues present in the same crystal. Crystal Structure: Kyanite belongs to the orthorhombic crystal system and typically forms in long, blade-like crystals. These crystals often have a striated or grooved appearance parallel to their length. Kyanite crystals can also exhibit twinning, resulting in distinctive crosshatch patterns. Hardness: Kyanite is relatively hard, with a Mohs hardness rating of 4.5 to 7. This makes it suitable for use in jewelry, although care should be taken to protect it from scratches and hard impacts. Cleavage: Kyanite exhibits perfect cleavage in one direction parallel to the length of the crystals. This means that it can be easily cleaved or broken along these planes, which can influence how it is cut and shaped for use in jewelry. Transparency: Kyanite is typically translucent to opaque, although some higher-quality specimens may exhibit greater transparency. The transparency of kyanite can vary depending on factors such as color, clarity, and the presence of inclusions. 2. 3. 4. 5.
1. Chatoyancy: Some kyanite specimens may display chatoyancy, also known as the "cat's eye" effect. This phenomenon is caused by the presence of fine, needle-like inclusions that reflect light, creating a luminous band of light across the surface of the gemstone when it is properly oriented. Metaphysical Properties: In metaphysical and spiritual traditions, kyanite is believed to have several properties, including: Alignment: Kyanite is thought to align and balance all chakras, facilitating the flow of energy throughout the body. Meditation: It is believed to promote deep meditation and enhance psychic abilities. Communication: Kyanite is associated with improving communication skills and fostering honest expression of thoughts and feelings. Healing: Some believe that kyanite has healing properties that can aid in physical, emotional, and spiritual healing processes. 2.
