These are AA-grade Agate raw geodes from Minas Gerais, Brazil, sold by the piece or by the pound. Each small geode is banded chalcedony hiding a hollow pocket of crystal inside its rough shell. Pieces run 0.75-1.50 inches at Mohs 6.5-7, sourced through a community partnership. A favorite protection stone for gifting and crystal grids.
Agate is a chalcedony (quartz variety). It is one of the most diverse and widely collected mineral groups, with dozens of named varieties based on color, pattern, and origin.
These geodes come from Minas Gerais, Brazil. Worth knowing: a lot of the agate on the market is dyed. What we carry is natural and untreated.
Agate is traditionally a stone 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 and sacral chakras. If that resonates, keep a piece in your pocket during the day for a steadying presence. Let it become part of your own quiet routine.
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.
Agate 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.
Natural agate from Minas Gerais, Brazil. These are untreated. Most colorful Brazilian agate sold as slices is heat-treated or dyed; these raw nodules are left in their natural state.
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 1.5 inches on its longest side and weighs 5 to 20 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.
Minas Gerais, Brazil. The state has been a major agate source since the 19th century. 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.
