2. Jade needs to be wiped frequently. Daily maintenance needs to be cleaned with clear water to remove dust and dirt, and then dried with a clean and soft cloth; It is best to put it on or take it off in a safe place such as sofa and carpet. Wear jade pendant, pay attention to check whether the red rope and necklace are firm, and replace them in time if they are damaged.
3. Human sweat can clean jadeite. Some people think it's best not to wear it when sweating a lot in summer. Their reason is that jade can't be stained with oil, and oil will seep into jade along its natural cracks, which will affect its luster.
4, jade bracelets need to be worn often. Jade bracelets can only rub against the joints in the wrist if they are worn frequently, thus playing a health-care role.

Reasons for the formation of jadeite:
Jadeite is a dense and massive aggregate formed by countless fine fibrous mineral crystallites, mainly jadeite. There are four main views on the formation of jadeite in nature:
The first view is that it is the desilication product of residual granite slurry that magma intruded into ultrabasic rocks under high pressure.
The second view is that primary albite is decomposed into jadeite during regional metamorphism; Or that albite first formed glaucophane schist with low metamorphic degree and then further metamorphic jadeite under the action of compressive and torsional stress and low temperature caused by plate collision.
The third view holds that granite veins and light gabbro veins were formed by metasomatism under the pressure of 12 ~ 14 kPa under the action of hot water solution with high sodium chemical potential.
According to the discovery of water-methane-jadeite three-phase inclusions in jadeite rocks, the fourth view is that jadeite is crystallized from the silicate melt of jadeite, which comes from the alkali-containing pyroxene layer widely existing in the mantle of 300 ~ 400 km.
