This is a very beneficial stone, but as always, don't wear it just after knowing its benefits. There should be a detailed analysis done of each stone in regards to the birth chart before determining whether one should wear it or not. Panna or emerald in English, helps make the mind stronger. It makes your memory stronger, makes you bold, and also makes you a better conversationalist. People whose Mercury/Buddh is weak, but in a state of giving can wear Panna. You can wear it to make your mind sharper. However, if your Buddh is the lord of the 3rd, 6th, 12th or 8th house, then you should not wear this stone.You can wear Panna, if Mercury is your mukhya graha/main planet, provided Mercury is not seated in a negative house and is already too strong, in which case it will cause you problems.
