Coral (Moonga)
Coral, popularly known as Moonga in Hindi and Sanskrit, is one of the most powerful gemstones recommended in Vedic astrology. It represents Mars (Mangal), the planet of courage, strength, determination, action, confidence, energy, and protection.
Red Coral is an organic gemstone formed from the skeletal structure of marine coral colonies belonging to the genus Corallium. After harvesting, the coral branches are polished into gemstones suitable for jewellery and astrological use.
Coral (Moonga) – The Gemstone of Mars
Unlike mineral gemstones, Red Coral is an organic gemstone formed naturally by marine coral polyps in the depths of the sea. Since ancient times, it has been regarded as a symbol of bravery, vitality, success, and protection from negative influences.
When recommended after a thorough horoscope analysis, a natural Red Coral may help strengthen a benefic Mars, improving confidence, determination, leadership, physical energy, and the ability to overcome obstacles.
For astrological purposes, an ideal Red Coral should have:
