Black Obsidian Tumbled Stone - 10-20 mm

Black Obsidian Tumbled Stone is a smooth, polished natural glass in deep jet black with a bright, glassy lustre. Each Black Obsidian piece is a rounded, hand-filling tumble with a clean, reflective surface. The stones suit a pocket, a bowl, or a grid.

Black Obsidian is traditionally associated with protection, grounding, and transformation, and it is commonly used as a strong, clearing stone. Many people carry a tumbled piece or keep one in a working or meditative space. Its bold black finish makes it a striking, grounding gift.

As a natural glass, each Black Obsidian Tumbled Stone varies slightly in lustre and surface character, so no two pieces are exactly alike.

Geological Information
Black Obsidian is a naturally occurring volcanic glass, a silicon dioxide formed when silica-rich lava cools too quickly for crystals to form, with a Mohs hardness of 5 to 5.5. Its jet black colour comes from iron, magnesium, and other mineral impurities. Obsidian has a conchoidal, shell-like fracture that produces extremely sharp edges, a property that made it one of the most important tool materials in human prehistory, used for over 700,000 years. Sources include the USA, Mexico, Iceland, Italy, Japan, Turkey, and Armenia.

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
Black Obsidian is a natural glass at Mohs 5 to 5.5 and can chip to a sharp edge if knocked or dropped. Keep it away from harder stones and hard surfaces, and handle any chipped piece with care.
