Coral helps to minimize and stop the malevolence effects of the planet Mars. It is not a stone like Amethyst or Ruby, however, it is considered a valuable Gem. Pure corals are lighter and softer than duplicate ones. If you look at this stone in the mirror you would find fine granules.

If in your horoscope the planet mars appears in the 4th, 8th or 12th house, then an 8 Carat ring/pendant has to be worn in a gold ring. If there is a Chandrama or Mangal yog in your horoscope, then a 5 carat or 14 carat silver ring has to be worn. Coral has to be purchased on a Tuesday or made on a Tuesday.
