Dark Green Ocean Kyanite Stick Shape 1lb

Ocean Kyanite — sometimes called Dark Green Kyanite — is a teal to deep green variety of the aluminum silicate mineral Al₂SiO₅, with coloration driven by trace iron and chromium substitutions in the crystal lattice. It crystallizes in the triclinic system and displays the hallmark anisotropic hardness of the kyanite group: roughly 4.5 Mohs along the blade axis, up to 7 across it. These specimens present in the elongated stick habit typical of high-pressure metamorphic formation in schist and gneiss host rock. 1-pound lot.

Origin: Tanzania  |  Crystal System: Triclinic  |  Hardness: 4.5–7 (anisotropic)  |  Composition: Al₂SiO₅ (Fe/Cr-bearing)

Traditionally linked to the heart and throat chakras, ocean kyanite carries a grounding yet communicative quality — its dual-toned color reflecting the bridge between earth and voice.
