Navratna — The Nine Planetary Gemstones

In Vedic astrology each of the Navagraha has its own gemstone (ratna), and wearing the right stone is the classic remedy to strengthen a benefic or well-placed planet. Together the nine make the Navratna. Each page below gives the gemstone’s planet, benefits, who should wear it, and the right finger, metal, day and mantra — with a caution for the powerful stones that must be tested first.
