Emerald is a bright green to greenish blue coloured gemstone which is one of the very clear representations of the planet Mercury in the Jyotishshastra. Being pleasant to look at as well as endowed with properties to mesmerize anyone who sees it is the natural instinct of the gem. It is termed as Smarakata in Sanskrit and Pannain Hindi.
