1. Do not hit hard objects. The jade is easily broken after being hit. Sometimes the naked eye does not see cracks, but the molecular structure in the jade surface has been damaged, resulting in dark cracks, which will appear for a long time, greatly impairing its perfection and collection value. 2. Avoid dust and oil as much as possible. If there is dust on the surface of the jade, it should be cleaned with a soft brush; if dirt or oil stains are attached to the jade surface, it can be washed with warm soapy water and then washed with water. Never use chemical degreasers. For the heavily contaminated old jade, professional companies that produce and clean jade can use professional ultrasonic cleaning and maintenance. 3, jade pendants should be placed when not in use, it is best to put them in jewelry bags or jewelry boxes to avoid bruises. 4. Avoid contact with perfume, chemicals, soap or human sweat. Because the jade is exposed to too much sweat, it will be eroded and the outer layer will be damaged, affecting the original vividness. In particular, white jade-leather white jade is more resistant to sweat and oil. After wearing it, wipe it with a soft cloth. 5, do not set the sun for long-term direct. The jade sun exposure is experiencing thermal expansion, and the molecular volume increases, which will affect the jade quality. Therefore, it is more likely to be close to the heat source. 6, too dry environment is easy to evaporate water, thereby damaging the quality of jade. In today's time-changing landscape, the special and unique qualities of jade have long been rooted in the hearts of Chinese Chongyu and Aiyu. Jade represents beauty, dignity, perseverance and immortality.
