According to Jiang Buli's "The Case of the Theft of Cixi Mausoleum",' No.51 Night Pearl weighs 422 yuan and seven cents (now 133.4375 grams), and is worth 10.82 million yuan. According to Jo Yeo-jeong's Antique Guide, "In short, if all the funerary objects of Cixi are recovered to pay off the foreign debts, it will be enough to enrich the country. The pricing and valuation of the listing were precious prices at that time, and all the values were the valuations of Chinese and foreign antique collectors and jewelers from then to Xuantongyuan, which increased tenfold. In the late Republic of China, it was appraised again, and it will be increased by a hundredfold. Today, it is no longer possible to pay attention to it. '
