Obsidian Black Tumbled Stones
Black stones that have been tumbled to develop a smooth, glossy finish.
These stones have a uniform pitch black colour
Obsidian Black is formed by the rapid cooling of volcanic larvae. No crystallization occurs and the stone has glasslike characteristics. All our other stones contain a crystalline structure (macro-crystalline or cryptocrystalline). Obsidian is different in that its structure is non-crystalline.
Longest dimension is 5mm-15mm with average length about 9mm.
These are ideal for use in resin art.
Keep out of reach of children
All our products should be kept out of reach of children under 5 years and anybody who may tend to place items or liquids in their mouths should be supervised. Even packing can become a choking hazard.
