What is Ratna?
Ratna (Ratna, रत्न) — Ratna means gemstone in Vedic astrology. Each planet has an associated gemstone that, when worn correctly, strengthens the planet's positive influence.
In Vedic astrology, Ratna (gemstone) therapy is one of the most tangible remedial measures. Each planet is associated with a primary gemstone that resonates with its frequency: Ruby (Sun), Pearl (Moon), Red Coral (Mars), Emerald (Mercury), Yellow Sapphire (Jupiter), Diamond (Venus), Blue Sapphire (Saturn), Hessonite/Gomed (Rahu), and Cat's Eye/Lehsuniya (Ketu). Wearing the correct gemstone channels the planet's energy to the wearer, strengthening positive significations. However, gemstones amplify planetary energy in both directions — wearing a gemstone for a functionally malefic planet can increase problems. Therefore, gemstone selection requires careful astrological analysis.
Examples
Practical Application
Consult a qualified Vedic astrologer before wearing any gemstone. The stone should be of good quality, set in the prescribed metal, worn on the correct finger, and activated on the appropriate day during a favorable Muhurta. Some astrologers recommend testing Blue Sapphire under your pillow before wearing.
