Emerald, the green variety of Beryl, is the most famous and valuable green gemstone. Its beautiful green color, combined with durability and rarity, make it one of the most expensive gemstones. Deep green is the most desired color in Emeralds. In general the paler the color of an Emerald, the lesser its value. Very pale colored stones are not called Emeralds but rather “Green Beryl”. They are sometimes heat treated, which causes their color to turn blue and transform into Aquamarine. The name emerald comes from the Sanskrit word “marakata,” which means spring green. Through time, the emerald has been known as a symbol of truth and love. In ancient Greece and Rome, emerald was said to be the gemstone of the goddess Venus, purveyor of love and hope. On the other side of the world, emeralds were revered by the Incas and believed by the Egyptians to be a source of eternal life. Emeralds were considered to be a gift from Thoth, the ancient god of wisdom. The emerald is also known as a stone of intuition, associated with sight and the revelation of future events and truths.
