# Obsidian Polished Tumblestones

Natural polished tumblestones of Obsidian (naturally glossy black volcanic glass), tumbled smooth from rough rock.

### About these stones

**Obsidian.** A naturally formed volcanic glass, produced when felsic lava cools rapidly without crystallising. Conchoidal fracture and glassy lustre.

### Details

-   **Form:** Polished tumblestones
-   **Size:** small to medium, varies naturally
-   **Stones:** Obsidian
-   **Origin:** Naturally sourced rough rock, hand-polished

Each tumblestone is unique; natural variations in colour, shape, size and pattern are part of the character of working with real minerals.

### Care

Keep dry; some minerals (selenite, halite) are water-soluble and should never be soaked. Store in a soft pouch or padded compartment to avoid scratching softer stones. Wipe with a soft dry cloth if needed.

### Packaging

Supplied in a velvet pouch. Free UK delivery on orders over £30.

_Sold as a decorative item. We make no medical, therapeutic or other claims about the stones. [Read our full disclaimer](/pages/disclaimer)._
