In astrology, why is the red coral gemstone linked to the planet Mars?

The planet Mars (Mangal) is the significator planet of leadership, quickness, blood, swift/sudden decisions, and energy. In astrology, Mars is addressed as the commander-in-chief (Senapati). The red coral gemstone, unlike other gemstones, is not obtained from mines but is formed from living coral in the sea; therefore, it possesses natural life-force and energy. Astrologers believe that wearing this gemstone makes the positive traits related to the planet Mars more active. The most prominent reason for this is the creation of this gemstone from living coral itself.

The red colour is a symbol of enthusiasm, power, blood, struggle, and radiance. The colour of red coral reflects the perfect completeness of Mars's qualities, which is why ancient astrologers have addressed red coral as the gemstone of Mars. A native should wear red coral only after getting the position of Mars in the birth chart, as well as the significator position of Mars for that specific chart, properly studied by a proper astrologer.

When red coral is worn after proper study, it helps in increasing the self-confidence, decision-making ability, leadership, etc., within the person, and also proves helpful in curing blood disorders and physical pain.
