Navratna jewellery features nine gemstones, each representing a celestial body in Hindu astrology. These gemstones—Ruby, Pearl, Red Coral, Emerald, Yellow Sapphire, Diamond, Blue Sapphire, Hessonite, and Cat's Eye—are believed to bring balance, prosperity, and protection to the wearer. The combination of these gems is considered highly auspicious and is traditionally worn to harness the positive energies of the planets.
