Red coral and pearl are organic gemstones formed by living creatures in the sea. According to Indian Vedic astrology, red coral is associated with Mars and gives courage, confidence, and determination, while pearl is associated with the moon and gives calmness, creativity, and compassion. Wearing both gemstones together can boost health and wealth for those with the right planetary positions of Mars and moon, bringing fame, recognition, and protection from diseases. One should only wear this combination if advised by an astrologer as it can lead to great success or challenges depending on one's astrological chart.
