What is jade? Jade is moist, transparent and delicate, all of which are indispensable. In fact, jadeite rough, but not jadeite rough. The difference between jade and stone is quite big. Some people say that they can’t believe it is fake only after seeing similar shots of raw jadeite. In fact, real good jade has very good air permeability. You can see it with the naked eye, which shows that the jade is not fine enough. Some people say that jade cool is really cool, in fact, this is a kind of distortion, because in the past there were a lot of fake jade made of resin or glass, and it was so, in fact, it was not enough to find out the real one. There are many types of jade, divided by names such as Hetian jade, jade, grapefruit, etc. But there is a difference between jadeite and field jade according to the physical hardness of jade. Here, I have to mention that many friends in life say that the jade that may scratch the glass is indeed moving, but it is not. The main component of glass is silica, and the hardness of the glass enables a partition to be clearly identified. Glass is harder than jade, such as jade and field jade. The hardness of glass is less than jade, jade, and grapefruit. So I don't know the nature of jade after jade time. Don't mess with glass items, otherwise the jade is likely to be damaged.

Strictly speaking, a person can become a gemstone re-decorator after his or her gem minerals have been processed. Gemstones have the following conditions (this is the difference between ordinary stones):
1. Very beautiful, bright and pure color, transparent and flawless luster, or changing color rendering, color, star or cat special optical effects.
2. Sturdy and durable. Gem not only needs to be beautiful, but more importantly, remain bright and shiny with durability, must be well-strung (Mohs gemstones should be higher than 7), wear-resistant, and have good chemical stability.
3, rare. In rare gems you are given, even gorgeous gems, if the resource is widely distributed, its commercial value will be affected. For example, when amethyst was discovered in Europe centuries ago, it was regarded as a precious gemstone due to its novelty and beauty. However, when a large number of high-quality ores were discovered in Brazil, amethyst no longer had the name of a treasure. . Another example is the fine texture of jadeite, which sells for 20,000 US dollars per carat, and is more expensive than diamonds. It does not say that the performance is better than jadeite diamonds, but because the output is less than jadeite diamonds.
