These are A-grade Petrified Wood crystal chips from Mahajanga, Madagascar, sold by the piece or by the pound. Petrified wood is fossilized tree material, and even at chip size the original grain often shows in the surface pattern. Each chip runs 0.25-0.50 inches at Mohs 6.5-7, fully natural and untreated. A favorite meditation stone for crystal grids.
Petrified Wood is ancient organic material within the Silicates family, original wood replaced by silica over millions of years.
Sourced through a community partnership in Mahajanga, Madagascar.
Madagascar's petrified forests date back over 200 million years and are among the most significant fossil wood deposits on earth.
In the tradition, Petrified Wood shows up most often around grounding, patience, and a sense of deep continuity. It's traditionally linked to the Root and Sacral chakras. If that resonates, hold a piece during moments when you need to slow down and feel anchored. 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.
Petrified Wood sits at 6.5–7 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.

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. 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.
