1, try to avoid being contaminated with dust and oil. If there is dust on the jade surface, clean it with a soft brush; If dirt or oil stains are attached to the jade surface, it can be scrubbed with mild soapy water and then washed with clear water.

2. Jade pendants should be put away when not in use. It is best to put them in jewelry bags or jewelry boxes to avoid collision.

3. Avoid contact with perfume, chemicals, soap or human sweat. Because jade is exposed to too much sweat, it will be eroded, destroy the outer layer and affect the original bright chromaticity. Especially white jade-suet white jade is more resistant to sweat and grease, so it should be wiped with a weak cloth after wearing.

4. Don't set the sun for a long time. Jade will expand in the sun, and its molecular volume will increase, which will affect the quality of jade, so it is more taboo to be close to the heat source. Too dry environment is easy to evaporate water, and jadeite in dry environment will damage the quality of jadeite.

Identification method:

The following methods can be used for identification:

First, when you choose jade in a dazzling array of jade stalls, you can use local materials and drop a drop of water on the jade. If the water drop is dew, it will prove to be true jade if it does not disperse for a long time; If the water drops disappear at once, it means it is defective or fake.

Second, perception. You can touch it back and forth when choosing jade. If you feel cold and lubricated, it may be real jade, because real jade has this property.

Third, pick up your favorite jade and watch it in the light. If the color is clear and the green is evenly distributed, it means that it is real jade.

Fourth, if the jade merchant allows it, you can lick it with the tip of your tongue. Real jade tastes astringent, but fake jade doesn't.

Fifth, if you choose jade in the informal jade market, you'd better bring a magnifying glass. Because you can see the quality of jade with a magnifying glass. In general, jadeite is seen under a magnifying glass. If it is real jade, it is a good jade with few or no cracks. If there are many or large cracks, it is proved to be defective.
