Generally, jadeite can be divided into A, B and C goods. A goods refer to jadeite that is naturally produced and has not been artificially treated. Goods B refer to jadeite with poor color originally planted with water. After soaking in strong acid and alkali, the planting water and color are improved and impurities are removed. At the same time, the original rock structure of jadeite is destroyed and holes will appear.

In order to cover this hole and increase the strength of jadeite, jadeite B is often filled with organic glue or inorganic glue. C goods refer to colorless or light-colored jadeite ornaments that have been artificially dyed. Natural jade bracelets do not fade. If it fades, it means it has been dyed.

Extended data:

Consumers must pay special attention to the specific warranty period marked on the quality guarantee of jewelry and jade before deciding to buy. If the warranty period is longer than the national regulations, when encountering problems, consumers can make relevant compensation claims to the merchants according to the marks on the guarantee.

In addition, it is recommended not to touch the jewelry in the specialty store when traveling. Judging from the daily appraisal, most of the goods bought in this way are fakes and inferior goods. Another suggestion is not to buy online. Jewelry colors vary widely, and the price is even worse. Online shopping is too risky.
