In fact, this is related to the environment in which jade is located. The air humidity in the south is high, and there is a lot of water vapor. The water loss of jadeite is much slower than that in the north. In the past, Chang Xiangyu jewelry store would show some jadeite raw materials as samples to explain jadeite knowledge to customers.

On the one hand, the discoloration of jade bracelets may be caused by mutation, which may even make jade bracelets turn yellow and black, or even dry up, and finally the green becomes old and then black. At this time, more attention should be paid to maintenance, which is generally recoverable.

Improper maintenance, baking and firing of jadeite will increase its internal molecular volume, make jadeite abnormal, make jadeite lose its moist moisture, make its variety dry and its color lighter.

After wearing for a long time, the colored polishing powder on the surface of the jade bracelet falls off and the jade bracelet returns to its original color. Do not pay attention to maintenance when wearing it. If you don't pay attention to maintenance, the jade bracelet 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.

It's hard for a layman to tell, but its color is dyed and can't last. 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.

Because without your careful care, it will lose color. The human body often secretes some oil, so you can take a bath every day, but you can't wash your hands all the time. However, if these jade ornaments are worn close to the body for a long time, they will definitely be eroded by sweat stains.
