Red Coral (Moonga) stone is powerful and associated with the planet Mars, so wearing it without proper guidance may cause side effects. Some people may experience anger, aggression, restlessness, headaches, or disturbed sleep if the stone does not suit their horoscope. It may also create conflicts in relationships or increase impulsive decisions. Therefore, always consult a qualified astrologer before wearing Red Coral. Ensure the stone is natural, properly energized, and set in the correct metal, usually gold or copper. Wear it on the recommended day and finger to avoid negative effects and gain maximum astrological benefits safely.
