These are AA-grade Black Moonstone hand polished stones from Amoron'i Mania, Madagascar, sold by the piece or by the pound. Black Moonstone is a dark feldspar with adularescence, a floating blue-white sheen created by light bouncing between internal layers. Each piece runs 1.25-2.00 inches at Mohs 6-6.5, fully natural and untreated. A favorite intuition stone for bedside tables.
Black moonstone is a dark variety of moonstone, gray-to-black with the same internal flash (called adularescence) that makes regular moonstone glow from within. The darker base color makes the flash more dramatic.
Hand-selected from Amoron'i Mania, Madagascar.
In the tradition, black moonstone shows up most often around staying connected to your body and the moment, a sense of groundedness when things feel uncertain, and listening to the quieter signals. It's traditionally linked to the root and crown chakras. If that resonates, keep a piece in your pocket during the day for a steadying presence. Trust what feels useful and leave the rest.
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 Moonstone sits at 6-6.5 on the Mohs scale, about as hard as glass, so it handles daily use but will scratch against harder stones. Keep chemical cleaners away from it; they can etch the surface.
Natural black moonstone from Amoron'i Mania, Madagascar. No. The stone's color and optical sheen are entirely natural. No coating, irradiation, or treatment has been applied.
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 1.25 to 2 inches on its longest side and weighs 25 to 50 grams. About 16 to 24 pieces per pound at this size, and each option shows its piece count.
AA grade at large size means clearly visible, well-centered adularescence, consistent dark body color, a quality hand polish, and no significant chips or fractures. The larger surface area makes grading the sheen more stringent. 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.
Sourced from Madagascar, the world's primary supplier of Black Moonstone with strong adularescent sheen and dark body color. 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. AA 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.
