Black Obsidian Crystals UK | Volcanic Glass Stone

Black obsidian is a naturally occurring volcanic glass formed when lava cools rapidly. It is characterised by its deep black colour and high-gloss, almost mirror-like surface when polished. Raw edges are sharp; polished pieces have a smooth, glassy finish.

Our obsidian range includes tumblestones, carved pieces and jewellery. For dark stone jewellery, browse our dark stone jewellery collection. See also black onyx and tourmaline for similar tones. Free UK delivery over £30.
