Material: Blue-Green Kyanite 7mm Origin: Brazil Size: Approximately 7mm (±0.5mm) Wrist Size: Approximately 15.5cm (elastic) Weight: Approximately 17g 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 is called "ranshoseki" (blue crystal stone) in Japanese. Among kyanites, those with vivid color and transparency are of higher quality. If you observe kyanite closely, you can see many lines, which look like layers of crystals in a certain direction that are layered on top of each other. The hardness changes depending on the direction from which force is applied to these layers. Due to this property, it is called "disthene," making it very difficult to process. The word "kyanite" comes from the Greek word "kyanos," meaning "blue." Product Number: BG6119-7
