Blue Obsidian Tumblestones

Pretty blue Obsidian tumblestones, measuring approximately 15-25MM long.

Blue Obsidian is sometimes incorrectly sold as natural volcanic glass. However, these tumblestones are not - they are an even coloured, manmade light blue glass.

Again - these are a blue man-made glass. While natural Blue Obsidian does exist, it is very, very rare and we have never seen a clear piece. It is usually a blue tinge to a completely opaque piece.

These tumblestones make a good decorative item when placed in a small bowl or a vase. They are perfectly suitable for use in a fish tank or an aquarium, being made of glass. Because of their light colour and clarity, they make an interesting contrast stone for a lot of things, especially darker and much lighter stones.

    What are tumblestones?

    Tumblestones are stones that have been put in spinning barrels with an abrasive compound for weeks or months. This slowly rounds off the rough rock and corners – the stones are then cleaned, and placed with a less abrasive grit. This happens several times until the stones are placed into a barrel with a polishing compound for their final polish.
