To buy a jade bracelet of more than 2000 yuan, you must have an appraisal certificate with photos. After carefully checking that the photos are consistent with the real thing, the objective description on the appraisal certificate should be taken as an important reference (some appraisal certificates with photos are also available below 2000 yuan); But it is more important to look at the real thing: species (the fineness of texture, that is, its structural structure, the finer the texture, the better), water (its transparency, jade from opaque to transparent), color (the color of jade depends on your preference), and work (jade carving is mainly reflected in ornaments, playthings, pendants, etc.).
Moreover, especially the bracelets, if I choose them myself, I will hang them with a string and knock them with an agate stick (or other bracelets). The better sound is crisp and melodious, indicating that its structure is relatively dense, and there are no stripes and cracks. However, BC goods are not as crisp and melodious as A goods because of their loose internal structure corroded by strong acid and alkali (of course, there are some natural A goods with poor texture or small cracks).
It's just a personal experience. I hope I can help you.
