The jewelry and jade industry in Taiwan Province Province has always enjoyed a high reputation, and the jade bracelets sold in duty-free shops generally undergo strict inspection and screening to ensure their quality and authenticity. So the jade bracelet you bought should be genuine.
However, even if you buy in a regular store, there may be some quality problems or manual handling. Before buying, I suggest you know the relevant jewelry knowledge first, so as to better judge the authenticity and quality of jade bracelets. At the same time, in order to avoid buying fake and shoddy products, you can pay attention to the logo of the gem appraisal institution on the product label and learn more about the quality and authenticity of the products from the sales staff.
