Worry Stones are engraved with a semicolon. If you know someone who is struggling, or if you’re struggling with life yourself, the stones can be great additions to your lifestyle. The key concept of a worry stone is that by holding or rubbing it, it promotes calm, eases anxiety, depression & negativity. Pictured: Tigers Eye, Rose Quartz, Jade, Clear Quartz & Moonstone. Each one is stamped with a semicolon to promote mental health awareness.
