Artificial nose rings, usually made of lightweight materials like aluminium and imitation stones, play an important role in traditional Indian dance forms like Bharatanatyam. These ornate nose rings, known as "nathu or nath bullaku," in India, are worn by female dancers to enhance their facial expressions giving more authenticity to their dance performance.They come in various sizes and designs, complementing the dancer's costume and jewelry. The nathu accentuates the engaging and graceful hand and eye movements, helping convey emotions and telling a story through the dance.
