Emerald Gemstone, or Panna Ratna, is considered as a highly auspicious stone in Vedic as well as western astrology. According to Indian astrology, it belongs to the planet Mercury or Budh Grah. It is mainly worn to gain wisdom, intelligence, good health, and professional prosperity. On the other hand, western astrology privileges it to be the birthstone of may month.
