Welcome to the forum,
Referring your post, first thing what i would advice is already you are wearing wrong gemstones together like Yellow sapphire and emerald, these two gemstones are not supposed to be weared together as they deadly against each other. And now you want to wear amethyst which is a semi-precious substitue of saturn, and already you are wearing ruby for Sun, and even here you are wearing anti-gemstone / enemical gemstone to ruby. Have you taken right advice from the right astrologer?
My suggestion for you at the moment would be to share your birth details here like date, time, place of birth. And for particular problem you want to go for gem therapy / for general purpose?
GOD BLESS!!!
