In fact, it can be called high-grade jewelry, most of which are precious stones. Perhaps everyone has heard of the existence of gems more or less, but few people actually see them. This is because gems are very rare on earth. I remember when I was a soldier, a comrade-in-arms once told me that it is very likely that gems will not be found in the jade mines in their hometown for decades or even hundreds of years, but once they appear, they are absolutely priceless. Throughout history, any one of them. Of course, in addition to precious stones, the following kinds of jewelry can also be called high-grade jewelry:

1, diamond

Although most of the diamonds we see at present are artificially made, if there are natural diamonds, they can definitely be called high-grade jewelry, and the bigger the diamonds, the higher the value. This is because the density of diamonds is very high, the cutting process is very difficult and the loss is quite large. Often a diamond appears, and less than 2/3 remains after cutting.

2. Jade

From the perspective of the whole world, only we in China use jade most commonly and widely. This is because the ancients especially liked to wear jade, thinking that a good piece of jade can attract money and ward off evil spirits, and the jade worn varies according to the level of people. Therefore, in movies, we often see that if a powerful person accidentally falls into poverty, he will exchange the jade he wears for money or mortgage, and jade is also a relatively high-standard jewelry in the jewelry industry.

3. Emerald

Jade is a kind of jewelry in the field of jewelry, which is second only to jade. The formation of jade is similar to that of jade, but compared with real good jade, jade may be slightly lower than jade. This is because there are many inferior jadeites, but the real good jadeites are relatively rare. Sometimes the really good jadeite is even more valuable than most jadeites.
