Blue Onyx Tumbled Stone - 15-35 mm

These Blue Onyx Tumbled Stones are polished into smooth, rounded forms in an even blue, with a soft, refined surface. Tumbling gives them a consistent, gently lustrous finish suitable for pocket stones, display bowls, or regular tactile handling. The tone of blue is consistent through the treated material, with slight variation from stone to stone.

Blue Onyx is traditionally associated with Calm and Stress Relief, its cool blue tone linked with steady focus supported by calm emotional grounding. It is commonly kept for Clarity and Focus, its Throat and Third Eye associations emphasising composed, clear expression.

Because this is a treated natural material, the exact tone of blue and the size vary from stone to stone, so the piece you receive will be uniquely its own.

Geological Information
Blue Onyx is a trade name commonly applied to dyed blue calcite rather than true chalcedony onyx. It is composed primarily of calcium carbonate with a Mohs hardness of approximately 3, which makes it significantly softer than true quartz-based onyx. The blue colour is produced through dye treatment applied to pale calcite material, with the intensity and tone varying according to the process and source material; the dyeing is the industry standard for this material and the colour is generally stable. Blue Onyx carries the broader onyx tradition through its material base, though the blue form is a modern commercial product. Principal sources include Brazil and India.

AuturaSol Standard
Each natural stone is selected for its authenticity, geological integrity, and energetic clarity. Natural variations in colour, structure, inclusions, and surface features are inherent to geological materials and contribute to the individuality of each piece. Any known treatments, enhancements, stabilization, or man-made characteristics are clearly disclosed within the product information where applicable. Every piece is inspected and photographed to reflect its true character; however, lighting conditions, screen settings, and natural variation may cause slight differences in appearance. If you have any questions about a piece before completing your purchase, we're always here to help. Where authenticity meets beauty, we tell you exactly what you're holding.

Care Note
Blue Onyx here is dyed calcite, soft at Mohs 3 and sensitive to acids and water. Keep it dry, wipe with a soft dry cloth only, and store it away from harder stones to prevent scratching.
