Extraordinary specimen of deep blue bladed crystals of kyanite with quartz from Barro do Salinas, Minas Gerais, Brazil. I have seen very few kyanite specimens as striking in composition as this one. Excellent condition. The longest blade is 10.5 inches (26.7 cm) long. Overal measures 10.5 x 4 x 2 inches ( 26.7 x 10.1 x 5 cm).
