The specific star sign or zodiac sign that should wear a navratna ring is determined based on an individual's birth chart and astrological consultation. Each person's birth chart is unique, and the recommendation of gemstones may vary depending on their planetary positions, strengths, and weaknesses.
Generally, the navratna ring is associated with the following gemstones and their corresponding planets:
1. Ruby (Manikya) - Sun
2. Pearl (Moti) - Moon
3. Coral (Moonga) - Mars
4. Emerald (Panchamukhi) - Mercury
5. Yellow Sapphire (Pukhraj) - Jupiter
6. Diamond (Heera) - Venus
7. Blue Sapphire (Neelam) - Saturn
8. Hessonite (Gomed) - Rahu (the north lunar node)
9. Cat's Eye (Lehsunia) - Ketu (the south lunar node)
However, it's essential to note that wearing a navratna ring should not be based solely on star signs. A qualified astrologer or a gemologist should examine an individual's birth chart and analyze their planetary positions and energies to make personalized recommendations regarding which gemstones are most suitable and auspicious for them.
It is also important to consider the quality, authenticity, and proper setting of the gemstones when choosing a navratna ring. Consulting a reputable astrologer or gemologist can help ensure that you obtain the right combination of gemstones and that they are worn in a way that is consistent with astrological principles.
