The Navaratnas are most powerful products in astrology. They have different types of stones and pearls, such as pearl, emerald, diamond, cateye, and sapphire to help receive cosmic power from heaven or the supreme soul.
In Hindu astrology, earth is considered the centre of the universe and the nine planets are the navagrahas. Each of these planetary positions supposedly have an influence throughout an individual’s course of life. Hence, wearing these nine gems is said to provide an astrological benefit. It is also said that these gems potentially may have both positive and negative influences on human life, therefore should be worn only after consulting an astrologer. Similar to the beliefs held in birthstones, the benefits of wearing such accessories has not been scientifically quantified.
Symbolically and astrologically, the nine gems are believed to represent the nine astrological bodies:
Ruby (Manikyam or Padmarag): Sun
Natural pearl (Mukta or Moti): Moon
Red coral (Moonga or Pravalam): Mars
Emerald (Marakatam or Panna): Mercury
Yellow sapphire (Pushparagam): Jupiter
Diamond (Hira or Vajram): Venus
Blue sapphire (Indra-neelam): Saturn
Hessonite (Gomedakam): Rahu, the ascending lunar node
Cat’s eye (Vaiduryam): Ketu, the descending lunar node
Based on an individual’s Sidereal horoscope, either a single gem or a combination of compatible gems is advised to be worn to harness beneficial planets or counteract harmful planets. There are two views in this regard. Gems are also purported to have certain healing properties, although this has yet to be scientifically proven.
A gem which is cracked, fissured, devoid of luster, or appearing rough or sandy, should not be used at all. “If anyone wears a gem with many flaws (even) out of ignorance, then grief, anxiety, sickness, death, loss of wealth and other evils torment them.”- Sri Garuda Purana: Chapter 70, Verse 19.
