Red Coral (Moonga)

Red Coral, known as Moonga in Hindi and Praval in Sanskrit, is one of the nine sacred Navratna gemstones. Unlike mineral gemstones, Red Coral is an organic gem — formed from the skeletal remains of marine polyp colonies (Corallium rubrum) found in the depths of the Mediterranean Sea, Japanese seas, and parts of the Pacific Ocean.

Its deep, fiery red colour is entirely natural, ranging from pale pinkish-red to deep ox-blood red, and has no crystalline structure. At Ratna Kendra, Lucknow, we source only certified, untreated natural Red Coral — primarily Italian and Japanese origin — to ensure authenticity and maximum astrological efficacy.

Spiritual & Astrological Significance

In Vedic astrology, Red Coral is the primary gemstone of Mars (Mangal Graha) — the planet of courage, ambition, physical energy, and warrior spirit. Mars rules the signs Aries (Mesha) and Scorpio (Vrishchika). 

Red Coral is prescribed to strengthen a weak or afflicted Mars in the birth chart, and is especially recommended for those suffering from Mangal Dosha — a planetary condition believed to cause obstacles in marriage, health, and career. Beyond Vedic tradition, Red Coral has been used as a protective talisman for centuries across Mediterranean, Arab, and Indian cultures, believed to shield the wearer from negative energies and evil eye.
