These are A-grade Black Kyanite raw crystal blades from Minas Gerais, Brazil, sold by the piece or by the pound. Black kyanite is an aluminum silicate that grows in fan-shaped bladed sprays, with hardness that varies by direction. Each blade runs 1.50-3 inches at Mohs 5-7, fully natural and untreated. A favorite cleansing stone for meditation spaces.
Black Kyanite is a kyanite (aluminum silicate).
Discovered and named from the Greek 'kyanos' meaning 'dark blue.' Black varieties are less commonly sought than blue kyanite but have gained popularity in crystal healing circles.
Our raw pieces are sourced from Minas Gerais, Brazil.
Those who work with black kyanite often turn to it for a sense of groundedness when things feel uncertain, cleansing, and staying connected to your body and the moment. It's traditionally linked to the root chakra. If that resonates, set one on the floor near where you sit to read or work. How you use it is up to you.
These are traditional associations drawn from historical practice. This stone is not a substitute for medical or mental health care.
Offered as a starting point for your own practice.
Black Kyanite sits at 5-7 (anisotropic) on the Mohs scale, soft enough to scratch with a knife, so keep it dry and store it on its own. Keep chemical cleaners away from it; they can etch the surface.
Natural black kyanite from Minas Gerais, Brazil. Untreated.
You'll receive pieces from the same batch photographed, weighed to the amount you choose. Every piece passes our quality control and meets or exceeds what you see in the photos. Single specimens are listed separately and say so.
Each piece measures 1.5 to 3 inches on its longest side and weighs 5 to 25 grams. About 32 to 48 pieces per pound at this size, and each option shows its piece count.
Grades reflect visual quality within a batch. A is standard, with typical inclusions. AA shows stronger color, cleaner surfaces and tighter sizing. AAA is the top 10 to 15 percent of a batch. Every lot is inspected and graded by our team in Rockville, Maryland, not taken on the supplier’s word.
This batch is from Minas Gerais, Brazil. It came to us through a community partnership, one of the sourcing models we publish and stand behind.
Every lot is inspected and graded by our expert team before it is listed, not taken on the supplier's word. A on this listing means stronger color, cleaner surfaces and tighter sizing than the batch average. Pieces that miss the mark never reach the shop.
How We GradeSourced through a regional cooperative or community-based workshop. Processing and economic benefit stay local, which means more of the value reaches the people doing the work. We say what we know and where our tracing stops.
Our Sourcing StandardsEverything we sell is natural in origin: never synthetic, never dyed, never coated. Where a stone has been heated, irradiated or stabilized, which is common in the trade for some species, we say so on the listing. If a piece is not as described, return it within 90 days of delivery.
