Emerald has been one of the precious gems since ancient times. According to legend, 6000 years ago, someone in Babylon dedicated it to the Statue of Liberty. In ancient Babylon in the Persian Gulf, women especially like jade ornaments. Thousands of years ago, ancient Egypt and ancient Greeks also liked to make jewelry with emeralds. People in China also like jade. Emperors in Ming and Qing dynasties especially liked jadeite. Ming Chengzu regards it as precious as a golden cat's eye, and there is a saying that "the ceremonial crown needs a cat's eye jade". The jade belt of the Wanli emperor of the Ming Dynasty is inlaid with a very large emerald, which is now hidden in the Dingling Museum of the Ming Tombs. In addition to a large number of pearls and other precious stones, there are two emeralds weighing about 5 yuan.
