About Red Coral :-Red coral, the common name given to a genus of marine corals, Corallium. The distinguishing characteristic of precious corals is their durable and intensely colored red or pink-orange skeleton, which is used for making jewelry. Red corals grow on rocky seabottom with low sedimentation, typically in dark environments—either in the depths or in dark caverns or crevices. The original species, C. rubrum (formerly Gorgonia nobilis), is found mainly in the Mediterranean Sea. The Red Coral Stone also known as Praval or Moonga is the Gemstone of Mars/ Mangal as per Indian Vedic Astrology. Mars is the planet of energy, vitality, blood circulation and ambition and the Red Coral is worn to boost the energy of Mars in the horoscope.
