Emeralds have been believed to symbolize fidelity and goodness. According to legend, emeralds strengthen the owner's memory, quicken the intelligence and assist in predicting the future. The Moguls of India, including Shah Jahan, the builder of the Taj Mahal, loved emeralds so much they inscribed them with sacred text and wore them as talismans. Some of these sacred stones, called Mogul emeralds, can still be seen in museums and private collections to this day. One example is a 78 carat deep green emerald which has an ancient Persian inscription around its edge stating: "He who possesses this charm shall enjoy the special protection of God".
