You are a cool communicator with a soft speech and you can impress people easily with your behaviour and tender approach.

As per your chart, the Blue Sapphire (Neelam) is not suitable to you at all and you need to stay away from that gem. But to get the advantage of Saturn's effect and blessings the Beeja mantra of Saturn is as good or better as the gem itself, which you can recite everyday, which is given below:-

ऊँ प्रां प्रीं प्रौं सह शनैश्चराय नमः ऊँ शं शनैश्चराय नमः

Om Praam Preem Praum Sah Shanaishcharaaya Namah Om Sham Shanaishcharaaya Namah

Best Wishes.
