Which Gemstone´s for me?

[Tulsidas]

I would like to improve my horoscope with gemstones.
I'm prepared to buy good quality gemstones.
I have a Computer-program that said I can wear diamond, blue sapphire and emerald. First I had no doubt, but then I read some books about that topic and understood that I should consult a qualified person to be sure.
I would be very thankful for help.
