The Emerald Stone is the astrological stone for planet Mercury in Vedic astrology and is said to make you intelligent, communicative, and prosperous. But, wearing Panna without astrological guidance can have adverse results on some people. In case the planet Mercury is weak, afflicted, or does not suit you, the gemstone will lead to problems like confusion, overthinking, nervousness, unstable finances, and issues with communication. Some people might even develop emotional imbalance or problems in their relationships. Therefore, Vedic astrologers always suggest analyzing your Kundli before putting on any Emerald stone.
