Ms./Mr.Sonu
Jupiter is in the star and sub of Rahu in 10th house (profession, career). Jupiter is also signifying 6th house. The gem stone which is governed by Jupiter is Topaz. On any thursday, You can wear it (around 5 to 6 carots) studded in gold on the little finger (right hand) after performing pooja to Lakhmi narasimha or Lakshmi narayana. Before going for topaz, wear the yellow coloured clothes and observe. If it is good, then think of Topaz.
Another planet is of Ketu. Ketu is signifying Mercury in 10th house. Ketu is more powerful than Jupiter. So Ketu governs cat’s eye. Its symbolic god is Ganesh. You can wear it in 2 to 4 carots studded in gold or silver. It should be worn on right hand ring finger.
Don’t go for Venus or Saturn, as they are significators of 8th house, which is not good.
Good Luck
