Ritual
A yellow sapphire should be bought on a Thursday, in an ascending cycle of the Moon and
when Pushya Nakshatra is present. If the nakshatra is not Pushya, then Punarvasu, Vishakha,
or Purva Bhadrapad are also auspicious for buying a yellow sapphire. The gem should be
given to the jeweler on the same day, between sun rise and 11.00 A.M.
The best time to wear a yellow sapphire ring is in the early morning.
Before wearing the ring for the first time it should be immersed in cow's milk for a few minutes
and then it should be washed in rainwater, spring water, or water kept in a copper pot over
night. After it has been washed, the ring should be placed on a yellow cloth upon which a
Jupiter Yantra has been drawn with roli and a yantra (or idol of Jupiter in gold) engraved on a
silver plate should be placed on the same cloth. One should offer flowers and incense to the
engraved yantra and to the stone that has been set in the ring and then recite the mantra of
Jupiter.
Mantra
Aum Brim Brahaspataye Namah Aum
The mantra should be recited either 108 or 19,000 times, as prescribed, and then the wearer
should meditate on the gemstone as a symbol of Lord Jupiter. After meditation the ring should
be worn on the first finger, which is the Jupiter finger, otherwise on the ring finger of the right
hand.
