The planet Mars is linked with red coral, or moonga, in Vedic astrology. The blazing planet Mars is a representation of bravery, ardor, and resolve. The wearer of a 4 carat red coral is said to gain greater self-assurance, power, and the capacity to conquer challenges by channeling this energy. Those who are facing Mangal Dosha, a Vedic astrological notion linked to marital difficulties, are also said to benefit from it.
