From ancient times to the present, pawning jade has remained a traditional business preserved by pawnshops. The professional requirements for pawnshop staff to authenticate and evaluate jade are extremely high. Appraisers need to be well-versed in the jade market trends, including: the price of raw stones, the cost of carving techniques for objects such as pendants, bracelets, and display pieces, renowned jade carvers, their works, and the pricing of these artists' creations. They should also know and understand the history of jade artifacts, the differentiation between ancient and modern jade, examining the decorative motifs and shapes of jade items to determine their dynasty of origin, and the methods of jade crafting (modern techniques versus traditional techniques), etc.
