Born from cooled volcanic lava, black obsidian is a glossy, jet-black natural glass with a sleek, modern finish. Our collection features obsidian bracelets, polished tumbles, pendants and carved pieces. Bold and smooth, it pairs beautifully with other dark stones; just handle the edges with care, as glass can chip. Free UK delivery over £30.
