Vedic gemstone prescription is an ancient science rooted in optical light refraction and planetary wavelengths. Each natural gemstone corresponds to a specific graha energy:

- **Yellow Sapphire (Pukhraj):** Expands wisdom, luck, and Jupiterian grace.
- **Blue Sapphire (Neelam):** Channels Saturnian discipline, focus, and rapid elevation.
- **Emerald (Panna):** Sharpens intellect, communication, and mercantile success.
- **Ruby (Manik):** Enhances leadership, vitality, and solar confidence.

### Essential Wearing Guidelines
For a gemstone to yield positive resonance, it must be untreated, eye-clean, set in the prescribed metal (Gold, Silver, Panchdhatu), and energized through proper Vedic Beej Mantras on an auspicious Muhurat.
