What gemstone(s) are good for me?

Hello,

I wish to learn about the gemstones I should wear in order to improve my life in alln aspects – career, love, health and more.

I understand yellow sapphire is a pretty good stone for me, but I want to know if it’s the best stone. Also, what are some others I can consider? Is opal or tourmaline one of them? 

I also would want to find out more about myself and life chart. How can I go about doing that?

These are my details:

DOB: 30/10/89 
TOB: 10:51am
POB: Singapore

Thanks so much.
