Obsidian Skull

 The guardian stone with the protective embrace of a
 dependable father, is a powerful force in dispelling
 negativity and repelling curses. Its grounding nature clears
 disorder from the body and soul, while its truth-enhancing
 qualities fearlessly expose flaws and weaknesses. As a
 steadfast companion, Obsidian assists in maintaining focus
 during daunting tasks, leaving nothing hidden from its
 watchful gaze.
