Material: Blue-Green Kyanite 7.5mm Origin: Brazil Size: Approximately 7.5mm (±0.5mm) Wrist Size: Approximately 15.5cm (elastic) Weight: Approximately 19g Features/Meaning: We have received rare, natural, uncolored green kyanite! Please be healed by the refreshing color and the characteristic fibrous shine of kyanite. Kyanite's Japanese name is "ranshoseki" (藍晶石), meaning "blue crystal stone." Among kyanites, those with vivid color, good color development, and transparency are of higher quality. If you observe kyanite closely, you can see many lines, which appear as layers of crystals in a certain direction, overlapping many times. The hardness changes depending on the direction from which force is applied to these layers. Due to this property, it is called "disthene," making processing very difficult. The word "kyanite" comes from the Greek word "kyanos," meaning "blue." Product Number: BG6119-75
