    Emerald Gemstone | Jyotish Gemstone of the communicative Mercury

    Emerald Gemstone | Jyotish Gemstone of the communicative Mercury

    Emerald's lush green has appeased souls and exited imaginations since ancient times. Its name comes from the Greek word for green, "Samaragdus". Mercury's Jyotish gem is the Emerald. It is one of the great five gems, known in Indian jargon as "pancharatna".

    Mercury is impartial, evocative, delightful, and youthful. He is famous for ready wisdom, and the power of communication. Related to our respiratory system, nervous system, and speech, Mercury makes people more skillful, clever and delicate. He is shown riding a lion with an elephant's trunk which points towards the dual nature of Mercury, readily apparent in those with Gemini ascendant. The lion symbolizes wisdom and the Elephant memory. In his hands Mercury has a bow and arrow to shoot his target, a disc for Vishnu, and a conch for liberation. He is the sport loving prince of the Congregation of Gods.
