Shungite Tumbled Stone Pendant

Shungite, matte black and carbon-rich, tumbled smooth. Traditionally kept close to anything electrical — desks, bedside tables, the pocket your phone lives in.

How to use it: Wear it or set it by the router. Shungite is porous: keep it out of long water soaks.

• Natural tumbled stone — every piece differs
• Cord included
• Wipe clean rather than soaking
