These are A-grade Black Tourmaline raw crystals from Minas Gerais, Brazil, sold by the piece or by the pound. Schorl, the black iron tourmaline, accounts for most tourmaline found worldwide and shows fine parallel striations. Each small piece runs 0.25-0.75 inches at Mohs 7-7.5, sourced through a community partnership. A favorite protection stone for crystal grids.
Black Tourmaline is dense, opaque, and architectural. The natural striations along its sides are signature, the kind of detail that catches light at an angle and reminds you these chunks formed under pressure deep underground.
Hand-selected from Minas Gerais, Brazil. The black color comes from iron and manganese in the crystal lattice. Tourmaline forms in long columnar crystals with three or six sides.
Black Tourmaline has long been worked with for grounding, protection, and clearing dense or stagnant energy. It's traditionally linked to the root chakra. Many people place a piece by a doorway, on a desk near a screen, or carry one in a pocket as a daily anchor.
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 Tourmaline sits at 7-7.5 on the Mohs scale, harder than a steel blade, so it handles daily carry and a quick rinse without fuss. The one thing that hurts it is sunlight: months in a bright window will fade the color, and it does not come back.
For quiet protection.

Natural black tourmaline 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 0.25 to 0.75 inches on its longest side and weighs 5 to 10 grams. About 48 to 72 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.
