Coral is governed by planet Mars. In astrology, great importance is attached to this planet, especially when considering a match for marriage. The position of the planet Mars in individual nativity decides the happiness or failure of conjugality. In Hindi and Sanskrit, coral is known as Moonga, Praval, Vidrum, and Angarakmani. In Persian, it is known as Mirzan. Coral is found in the sea. A good quality coral is shining red in color with a slight orange hue. It should be round or oval, or triangular in shape. A long, narrow coral should not be worn since it brings ill luck. White spots found on coral portend health problems to the wearer. A double shade in coral is considered inauspicious. The coral should be set in gold. Its weight should be between three to six carats.
