Navratna is the combination of nine auspicious gemstones associated with ‘Navagrahas’ or the nine celestial bodies of the solar system. Ruby is the gem for the Sun, natural pearl for the Moon, red coral for Mars, emerald for Mercury, yellow sapphire for Jupiter, diamond for Venus, blue sapphire for Saturn, hessonite for Rahu (ascending lunar node), and cat’s eye for Ketu (descending lunar node). Setting the nine gems in proper place is believed to confer various protective and beneficial powers to the wearer. Navaratna jewelry can balance the energies of the planets, promoting physical and mental wellbeing.
