Red Coral, also known as Moonga, is one of the most powerful astrological gemstones linked to Mars (Mangal). Its high price in India depends on rarity, origin, color, clarity, and certification. Premium quality corals mainly come from the Mediterranean Sea, especially Italian sources, making them limited and costly. Deep red, blemish-free, untreated stones command higher per-carat rates. Astrological demand further increases its market value, particularly for strong Mars placements in Vedic astrology. Certification, shape, and weight (carat size) also impact pricing. Because natural red coral is organic and scarce, authentic pieces are significantly more expensive than dyed or synthetic alternatives.
