Red Coral is the gemstone of Mars. It is classically recommended for Aries, Cancer, Leo, Scorpio lagna. Every other lagna needs the chart read first — the stone amplifies the graha either way.
Also known as: Moonga · Laal Moonga · Munga
A planetary gem is held to absorb and transmit the radiation of its graha, which is why it is the strongest intervention in the classical set — and the only one that can make things worse. It amplifies whatever the planet is already doing in your chart, so it is prescribed against a reading, never against a wish.
Red Coral is worn for Mars on a Tuesday, and is one of the gems most often sold to people whose chart argues against it.
Red Coral is Mars’s stone, one of the most prescribed of all planetary gems, worn for courage, physical strength and decisiveness.

Worn against the chart, Red Coral amplifies exactly what an afflicted Mars already does — aggression, accident-proneness and conflict. It needs a placement check first, not a shop assistant’s recommendation.
Carnelian · Bloodstone
Most charts should not wear Red Coral at all. It is prescribed only where the node's dispositor is strong, where it sits in an upachaya house, and for a specific purpose named by a qualified astrologer.
The accepted substitutes are Carnelian, Bloodstone. They carry the same caution as the primary stone: the substitute is cheaper, but it is the graha and not the price that decides whether it should be worn.
The mantra, the weekday fast and the charity are safe for anyone — they address Mars without amplifying it. Red Coral is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
