How Are Gemstones Recommended?

In Vedic astrology, gemstones are recommended based on your Moon sign (Rashi) and Ascendant (Lagna). The primary gemstone strengthens the ruling planet of your Moon sign, while a secondary stone supports the Ascendant lord. Each gemstone absorbs and transmits specific planetary energies that can enhance favorable influences in your life.

The Nine Planetary Gemstones

Sun: Ruby (Manik). Moon: Pearl (Moti). Mars: Red Coral (Moonga). Mercury: Emerald (Panna). Jupiter: Yellow Sapphire (Pukhraj). Venus: Diamond (Heera). Saturn: Blue Sapphire (Neelam). Rahu: Hessonite (Gomed). Ketu: Cat's Eye (Lehsunia). Each must be worn on the correct finger, in the right metal, on the designated day.

Important Precautions

Never wear a gemstone without proper astrological consultation. Blue Sapphire and Hessonite should be tested for 3 days before regular wear. Always use natural, untreated gemstones of minimum prescribed weight. Activate the stone with its mantra before first wearing. If a stone causes discomfort, remove it immediately.
