Emerald, called Panna in Vedic astrology, is linked to the planet Mercury (Budh), known as the quick-witted and intelligent prince among the Navagrahas. Mercury governs intellect, communication, speech, trade, and analysis, making Emerald the ideal gemstone for enhancing mental agility, articulation, and business success.
In Hindu mythology, Mercury is the son of the Moon and Tara (the wife of Jupiter), symbolising the union of mind and speech. Emerald channels Mercury’s vibrant and lively energy, promoting sharp intellect, logical thinking, and emotional balance. It is especially revered for aiding writers, speakers, businessmen, and students.
This lush green gemstone also offers calming and healing vibrations. It soothes the nervous system, improves memory, and promotes harmonious relationships.
