Sagittarius rising (Dhanu Lagna) is ruled by Jupiter, the planet of wisdom and teachers. The stones the tradition lists for this ascendant are yellow sapphire for Jupiter, red coral for Mars and ruby for the Sun. Mars and the Sun are both counted as friends of Jupiter in the classical scheme, which is part of why the list feels coherent. Mars has a small complication, since it rules the 12th as well as the 5th. This page explains each choice, the care a reader takes, and why the birth chart always comes ahead of a table.

Your life stone: the lagna lord
Yellow sapphire is the stone of Jupiter, the lagna lord for Sagittarius rising, with no difficult house attached. It is the plainest entry on this page. Tradition sets it in gold, worn on the index finger on a Thursday, though customs differ. Jupiter is exalted in Cancer and at home in Sagittarius and Pisces, so a Jupiter there is rarely a candidate for reinforcement. Jupiter in Capricorn, where it is weak, or one in a hard house, would be a better case for a reader to study. Jupiter’s themes of teaching, advice and generosity are also served by conduct, and many astrologers begin there before any stone is bought.
The stones of the 5th and 9th lords
Mars rules the 5th house, so red coral is the second stone, tied to learning, creativity and children. Mars also rules the 12th, making it a mixed lord, and a reader may therefore hold back until the chart has been studied. The Sun rules the 9th house, so ruby is the third, linked to fortune, the father and dharma. The Sun is a clean entry here, and the question is how strong it is. A Sun in Aries is exalted and needs little, while a Sun in Libra is weak. Both stones are conditional, not defaults, and the chart in front of the reader decides.
The stones usually avoided, and why
Venus rules the 6th house and the Moon rules the 8th, and neither owns a supportive house for Sagittarius rising. Diamond and pearl are therefore the stones astrologers usually avoid here, since a gem is meant to strengthen its planet and the aim is to strengthen the supportive ones. This is a general tendency. A Moon or Venus with an especially strong placement might lead a reader to hesitate over the usual advice, and it is not a statement that either stone is wrong. Mars is the mixed lord of the list. Rahu and Ketu rule no sign, so hessonite and cat’s eye are judged from where they sit.
How your own chart changes the advice
For Sagittarius rising, begin with Jupiter: its sign, its house, closeness to the Sun, and the planets that aspect it. Do the same for Mars and the Sun. Planets in the 6th, 8th or 12th house read differently from those in angles and trines. A weak Jupiter in Capricorn or a weak Sun in Libra might prompt a conversation about support, but a planet in its own sign or exalted might need none. The running dasha tells a reader which stone to raise first. A table cannot judge any of this, which is why it is only a starting list.
Timing: dashas and the stones
Timing in Vedic astrology runs on the Vimshottari dasha, in which each planet rules a major period of set length. For Sagittarius rising, the periods of Jupiter (16 years), Mars (7 years) and Sun (6 years) are where astrologers look first when the stones are discussed, since a gem is most often debated for the planet whose period is running or about to begin. The periods of Venus and Moon are handled differently: readers usually prefer conduct, mantra and patience through those years, and keep the stone question for later. The order of periods in a real chart starts from the Moon’s nakshatra at birth, so the Mahadasha calculator will show yours.
The older first steps
Every stone on this page has an older and cheaper counterpart in the tradition. For Jupiter the traditional day is Thursday, with respect for teachers and sharing what one knows as the matching habits. On Tuesday, the day of Mars, devotees often add steady exercise and keeping the temper in check. Sun has Sunday as its day, and rising early, greeting the morning light and keeping promises to elders is how many families keep it. None of this competes with a stone; it is where most readings begin, at no cost. For the mantras themselves, see the Navagraha mantras page.
