When people talk about jade cultivation, the word "cultivation" not only tells us that jade is a living substance, but also contains a lot of knowledge. The maintenance of jade jewelry can be summarized as follows: the hardness of jade is very high, but it is easy to crack after collision. Sometimes, although the cracks cannot be seen with the naked eye, the molecular structure in the surface of jade has been damaged, with dark cracks, which greatly damages its perfection and economic value. Avoid dust as much as possible. If there is dust on daily jadeware, it should be cleaned with a soft brush; If dirt or oil stains are attached to the surface of the jade, they should be brushed with mild soapy water, and then washed with clean water. Do not use chemical degreasing agent or degreasing fluid. It is better to put it in the jewelry bag or jewelry box to avoid scratches or damage. If it is high-grade jade jewelry, do not place it on the counter to avoid dust and affect the transparency. Try to avoid contact with perfume, chemicals, soap and human sweat. If jade is exposed to too much sweat and is not wiped clean immediately after wearing, it will be eroded, causing damage to the outer layer and affecting the original brightness. Especially the "glass ground" jadeite and white sheepskin jade, which also avoid sweat and grease. Jade should be protected from the sun, because the expansion of jade in case of heat will affect its quality. Hibiscus jade, crystal, agate, etc. may even burst under high heat. Wipe the accessories with clean and soft white cloth, not with dyed cloth or hard fiber cloth. Jade jewelry inlaid with diamonds, rubies, emeralds and other precious stones should only be wiped with a clean white cloth to remove grease, dust, etc., which helps maintain and maintain the original quality. Keep proper humidity. The quality of jade depends on a certain humidity, especially for aquabilite and crystal jade. The surrounding environment shall not be too dry.
