Kyanite is a collector’s favorite for one reason above all: its color. The finest crystals show a deep sapphire blue — sometimes with the same velvety saturation — at a far more accessible price. Nepal produces the benchmark material, with vivid teal and green-blue stones also emerging from East Africa.The mineral is famous for its dramatic anisotropy: hardness varies from about 4.5 along the crystal to 7 across it, demanding a skilled cutter — which makes well-faceted kyanite genuinely uncommon. Its strong pleochroism rewards video inspection, and every GEMIC listing includes footage of the exact stone offered.Our kyanite selection is entirely natural, examined stone by stone in the GEMIC Institute laboratory in Siem Reap and delivered with a gemological certificate stating species, weight and dimensions. Each kyanite is one of a kind: once it sells, the listing is retired forever. Orders ship worldwide with tracking and carry our 30-day return policy. Seeking a matched pair or a particular shade of Nepalese blue? Our gem hunting service can help.
