These are AA-grade Rainbow Obsidian tumbled stones from Jalisco, Mexico, sold by the piece or by the pound. Rainbow obsidian is volcanic glass whose banded sheen comes from nanoscale magnetite layers that split light at certain angles. Each piece runs 1-1.50 inches at Mohs 5-5.5, fully natural and untreated. A favorite emotional healing stone for meditation spaces.
Rainbow Obsidian is part of the volcanic glass family.
Named after Obsius, a Roman who reportedly first found it in Ethiopia.
We bring these tumbled stones in from Jalisco, Mexico.
Those who work with rainbow obsidian often turn to it for working through difficult feelings at your own pace, opening to connection, with yourself and others, and a sense of groundedness when things feel uncertain. It's traditionally linked to the root and heart chakras. If that resonates, hold one in your non-dominant hand for a few breaths when things feel shaky. 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.
Rainbow Obsidian sits at 5-5.5 on the Mohs scale, soft enough to scratch with a knife, so keep it dry and store it on its own. Keep chemical cleaners away from it; they can etch the surface.
Natural rainbow obsidian from Jalisco, Mexico. Untreated. The rainbow is natural light interference, not a coating.
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 to 1.5 inches on its longest side and weighs 10 to 30 grams. About 24 to 40 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 Jalisco, Mexico. It came to us through a direct source, 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 GradeWe work directly with the mine or workshop, with no intermediaries in between. The relationship is personal, pricing is transparent, and we can speak to each batch. 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.
