One thing you may not know is that the concept of "jewelry" is much bigger than that of "gem". Because gems are only processed, carved and polished jewelry raw materials, but jewelry can be seen everywhere, but it is far from enough to understand these knowledge. You also need to know some cold knowledge that jewelry circle experts know. Interested friends, we continue to look down!
1. Why does the jade counter always put a glass of water?
I believe many careful friends have discovered that there is always a glass of water in the jewelry counter of the shopping mall. People who don't know at this time will be very curious. Why? In fact, it is because jade can't live without water. Because the internal crystal structure of jadeite is extremely unstable, once it is heated and exposed to excessive light for a long time, it will lose a lot of water, which will not only make the color of jadeite look dull, but also not moisturize, eventually forming the phenomenon of running water.
But putting a glass of water can not only increase the humidity of the environment where jade is located, but also make it look more moist and shiny. A simple move can not only prevent the jade from "wandering", but also make the tender jade look better, killing two birds with one stone.
2, the most afraid of water is actually pearls!
Pearl is born in water and is also known as the "son of the sea", but it is very "afraid" of water. Everyone must be curious about why! Let me tell you more about it.
3. Black Pearl is not black.
What we don't know about "black pearls" is that black pearls are not as black as their names suggest, and none of the real "black pearls" are black. If the color is pure black, it must be dyed. Don't buy it. Because black pearls are mostly dark green, blue-black, purple-black, iron gray, silver gray and so on. Moreover, the main producing area of black pearls is Tahiti, where there are many kinds of pearls with dazzling colors.
