Intergrown kyanite crystal cluster from Brazil. The specimen consists of multiple bladed kyanite crystals grown in tight, intersecting aggregates, showing the characteristic elongated habit and strong longitudinal striations of the species. Color ranges from medium to deep blue with good saturation, combined with a bright vitreous to pearly luster on fresh crystal surfaces. The crystals are well exposed and form a compact, aesthetically balanced cluster, representative of classic Brazilian kyanite material.
