These are AA-grade Petrified Wood tumbled stones from Mahajanga, Madagascar, sold by the piece or by the pound. In petrified wood, silica replaced ancient tree tissue so completely that grain and growth rings survive in stone. Each piece runs 0.75-1.25 inches at Mohs 5.5-6.5, fully natural and untreated. A favorite grounding stone for pockets.
Petrified wood is wood that turned to stone over millions of years as silica replaced the original cellular structure. Good pieces still show the growth rings, the grain, the knots. Every piece is a record of a tree that lived a long time ago. Petrified Wood is associated with grounding, ancient wisdom, and patience.
Sourced directly from Mahajanga, Madagascar.
Those who work with petrified wood often turn to it for staying connected to your body and the moment, a sense of groundedness when things feel uncertain, and gentle, patient care for yourself. 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.
Petrified Wood sits at 5.5-6.5 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 petrified wood from Mahajanga, Madagascar. Untreated. A natural fossil; the silica replacement happened in geologic time.
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 0.75 to 1.25 inches on its longest side and weighs 5 to 15 grams. About 40 to 64 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 Mahajanga, Madagascar. 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.
