Obsidian or volcanic glass is a material with a unique formation, during which hot lava cools rapidly, e.g. in water or on the Earth’s surface. The process is so fast that the individual minerals do not have enough time to crystalize. This piece is from Mexico.

Rainbow Obsidian uniqueness: Rainbow obsidian is captivating for its dark, gently banded design. If the stone is cut in the right way, the light refraction on its tiny little layers provides marvellous rainbow-like effects.

Special conditions/ treatment: Obsidian is stable against most acids. However, be careful when handling with the stone, as it is fragile.

Use: Mini tumbled stones (chips) are used for the production of various decorative items and ornamental mosaics. Size 3 - 5 mm is also suitable as filling for small glass bottles.

About the product: We offer this product in 1 kg or 5 kg package; some "chips" are available in both variants. The product is packed in firm plastic bags.
