Coral is a precious gemstone which is found in the sea created by marine creatures named polyps and ruled by planet mars. This coral gemstone is beneficial for manglik dosha or mangal dasha. It is mostly red in colour but also available in white and orange colour. It is worn for wrongly placed or weak mars in horoscopes. If you don’t wear a ring then you can also wear it on a pendant. Coral comes from many countries but for astrology Italian and Japanese coral are more preferable. It protects from any type of mishaps, accidents, or bad incidents. It is good for blood related problems.
