Since you have not provided place of birth, only Moon chart could be generated. You are born with Moon placed in Gemini. The day you wre born Jupiter was Exalted and in D-9 also Jupiter is strong. Thus, you can wear Emerald but you don’t need to wear Yellow Sapphire. Still if you are suggested by a profound Astrologer for specific reasons you can wear Yellow Sapphire. in right hand ring finger and Emerald in pendent.
If you could provide your place of Birth then the suggestion could be more worthy.
Best wishes,
