Blue Onyx Tumbled Stone - 15-30 mm

Blue Onyx Tumbled Stone, a smooth polished piece in soft sky blue, often with paler banding and gentle tonal variation across the surface. Each stone is tumbled to a rounded shape and a calm, even polish. It sits lightly in the hand or pocket.

Blue Onyx is traditionally associated with calm, clear communication and easing of stress, and is commonly used as a soothing, settling stone. People often hold it during quiet moments, keep it on a desk to encourage steady focus, or carry it as a gentle, cooling presence. Its soft blue makes it a popular calming piece.

Each Blue Onyx Tumbled Stone is individual, so the depth of blue and the soft banding differ from one piece to the next.

Geological Information
Blue Onyx is a trade name for dyed blue calcite, not a true onyx. The base material is pale calcite, calcium carbonate, dyed to produce the blue colour, which is the industry standard for this material and is generally stable. Calcite is soft at Mohs 3 and acid-sensitive. The material is sourced mainly from Brazil, with some from 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 is soft at Mohs 3 and scratches easily, so store it apart from harder stones and handle it gently. As a calcite it is sensitive to acids and chemicals, so keep it away from household cleaners, perfume and prolonged water exposure, which can also affect the dyed colour.
