This is a natural agate reed oil diffuser from Minas Gerais, Brazil, cut from an agate nodule, hollowed for a removable oil tube. One face is polished flat to show the banding, the outer rind stays rough, and a chrome collar seats into the top. It weighs 2 to 3 pounds, Mohs 6.5 to 7. Reeds are not included.
Agate is banded chalcedony, a microcrystalline quartz that fills cavities in volcanic rock in slow concentric layers. Cut through and polished, a nodule shows those layers as lace, rings, and sometimes a small open vug where the growth never closed.
These diffusers come from a cooperative in Minas Gerais, Brazil. One face is polished to open up the banding, the outer rind is left rough exactly as it came out of the ground, and the interior is hollowed for a removable plastic tube.
Worth knowing: a great deal of the agate sold today is dyed bright blue, pink, or green. These are undyed, so the grays, creams, and rusts are the colors the stone formed with.
Agate is traditionally a grounding, steadying stone, associated with stability and a settled mind rather than any dramatic shift. It is linked to the root and sacral chakras.
As a diffuser it sits somewhere you pass daily, which suits a stone people keep for steadiness. There is no single right way to use it.
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. No. Much of the agate on the market is dyed bright colors. These are undyed, so the gray, cream, and rust banding is natural to the stone.
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 2.50-3.50" L x 2.50-3.50" W x 4.00-5.00" H and weighs 2 to 3 pounds.
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 lot 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.
