Emerald is a green gemstone whose color comes from traces of Chromium. If you are unfamiliar with rough Emeralds, you will find that the natural stones will vary in translucency and may contain many inclusions, patches and rocky veins. Emerald is the stone of successful love, bringing domestic bliss and loyalty. In groups of two or more people, Emeralds can encourage bonding and strengthen communication and understanding, helping each person to adequately express themselves without offending others. Emerald is used to balance the Heart Chakra.
