Why are you wearing Emerald, as Mercury is the 6th lord in your horoscope.
I feel you are already wearing too many stones. One thing I like to tell you that by simply wearing stones and doing other remedies your bhagya will not shine or change, Karma that is the integral part of Hindu philosophy is equally important. Therefore along with whatever astrology remedies that you do, do not forget that your luck will smile only when you put requisite amount of efforts in whatever you want to achieve. IF you wait for things to happen by themselves then you will only receive disappointments.
