Some emeralds in the market are B goods. The so-called B goods are ordinary jade, which is very realistic after being soaked in strong acid and alkali for about 1 month to form cracks, and then injected with green glue. Real jadeite feels cold and hot, and the texture is layered and uneven through light, but the fake one is the opposite. Wearing fake ones will also do harm to health, and some preparations inside will cause cancer.

It is necessary to find out the external and internal defects of bracelets, such as black spots, yellow spots and white "stone flowers", and consider the influence of these defects on aesthetics and value.
