To nullify the Manglik dosh one can take the assistance of the red coral gemstone. The red color brilliant coral stone astrologically affiliates with the planet Mars. It is believed that this stone preserves the positive powers emitted by the planet Mars within it.
And wearing this stone will help to kill the negative dosh of Mangal (Mars planet). To kill or ward-off mangal dosh one should wear a natural certified red coral gemstone ring in the third finger of the right hand on Tuesday Morning.
