Ruby (Manik)
Ruby (Manik) is the gemstone of the Sun in Vedic astrology. Traditionally set in gold and worn on the ring finger on a Sunday, it is linked with confidence, leadership and vitality.
Also known as: Manikya
The Sun stands for the self, authority, the father and vitality. A ruby is worn to strengthen a Sun that is helpful in the chart but weak. Gem lore prizes a deep, even, transparent red, and a natural stone whose treatment is disclosed.
By house lordship it is most often considered for Aries, Leo and Sagittarius ascendants, where the Sun rules the 5th, 1st or 9th house. Astrologers are usually wary of it for Gemini, Virgo, Libra, Capricorn and Pisces ascendants, where the Sun rules the 3rd, 12th, 11th, 8th or 6th, and careful with it for Cancer and Aquarius, where the Sun rules a maraka house (the 2nd or 7th).
A ruby should suit the whole chart: the Sun’s house, strength and aspects, and your running dasha. If the Sun is difficult in your chart, a ruby can feel too intense. Red garnet and sunstone are gentler, more affordable substitutes.
It is a traditional support, not a cure or a guarantee. Consult a qualified astrologer before buying, and notice how you feel in the first few weeks.
