What is the reason why the jade bracelet will change color?

1, do not pay attention to maintenance when wearing. If the jade bracelet is not maintained, it will be hot and cold, and the expansion and contraction of the jade crystal will cause looseness, and the gap between the crystals will increase, which will weaken the transparency and fade, leading to the discoloration of the jade bracelet.

2. The discoloration of the jade bracelet may be due to contact with sweat. Under the action of oil and sweat, the jade bracelet will become more and more moist, but at the same time, the texture will become more and more shiny, gradually deepening the color of the jade bracelet.

3. Jadeite bracelets change color because some jadeites will turn yellow and get old after being worn for a long time, which is called "variation" of jadeite finished products. This variety is due to the loose structure and obvious cracks on the surface of some varieties of jadeite, which will be attacked by external oil and dust after wearing for a long time.

4. What is the reason why the bracelet suddenly changes color? 1 may be normal discoloration. The jade bracelet comes into contact with human skin, and sweat penetrates into the jade mineral combination and fills the gaps between jade mineral particles, nourishing jade, and the green color of jade is more obvious.

It is difficult for laymen to distinguish, but its color is dyed and can't last long. Beautiful colors will gradually disappear when worn, showing the color before dyeing. Another reason is that the variety of jadeite is too tender and the structure is loose, which leads to head loss, dryness and yellowing, and looks like discoloration.

6. However, if these jade ornaments are worn close to the body for a long time, they will definitely be eroded by sweat stains. Therefore, those bracelets with poor texture will change color, which is probably caused by the invasion of these oils or sweat.
