These are A-grade Blue Calcite raw stones from Ambatondrazaka, Madagascar, sold by the piece or by the pound. Blue Calcite is a soft carbonate mineral in translucent pastel blue that splits along clean rhombohedral planes. Each piece runs 1-2 inches at Mohs 3, sourced through a community partnership. A favorite sleep stone for bedside tables.
Blue Calcite is a calcite (carbonate). Calcite varieties have been valued since ancient times.
These raw pieces come from Ambatondrazaka, Madagascar. It's soft (Mohs 3), so handle it with a little care, keep it dry, and store it in its own pouch so harder stones don't scratch it. Worth knowing: a lot of the blue calcite on the market is dyed and heat-treated. What we carry is natural and untreated.
In the tradition, blue calcite shows up most often around quiet, steady calm, working through difficult feelings at your own pace, and winding down and settling into rest. It's traditionally linked to the throat chakra. If that resonates, hold it for a few breaths before a conversation that matters. 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.
Blue Calcite sits at 3 on the Mohs scale, among the softest stones we carry, so handle it gently and keep it dry. Long soaks dull the surface, so keep any water contact brief and dry it fully.
Natural blue calcite from Ambatondrazaka, Madagascar. Untreated.
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 2 inches on its longest side and weighs 20 to 50 grams. About 12 to 20 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 Ambatondrazaka, 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.
