@ Soni,
Never wear Yellow Sapphire and Hessonite (Guru & Rahu) together evn if in different hands or parts of the body, unless you have a very specific reason and/or purpose to do so. Rahu maligns the wisdom of Jupiter and one’s religious tendencies and good luck usually suffers when worn together.
Wishing you good luck, may God bless you and above all????
Cheers
