Blue Kyanite - Brazil

These Blue Kyanite specimens showcase a striking range of blue tones, from deep indigo to vibrant sky blue, often presenting with a characteristic vitreous to pearly luster. A notable feature of Brazilian Kyanite is its tendency to form elongated, blade-like crystals with distinct striations running along their length, a direct result of its unique crystal structure. ¹ Furthermore, Brazilian Kyanite exhibits a fascinating physical property known as anisotropic hardness, meaning it has a Mohs hardness of 4-4.5 when scratched parallel to its length and 6-7 when scratched perpendicular to it, making it a truly distinctive and scientifically intriguing addition to any mineral collection.

Note:  The specimen if fragile/flakey and small pieces of quartz/kyanite will probably dislodge during shipping.
