"Plant" is one of the keys to measuring the quality of jadeite. It refers to the thickness and transparency of jade texture. The top grade is old, the second is new, and the old ones are better after processing.
Jadeite should look at the color under the conditions of good cultivation. This is what the jargon says is "the layman looks at the color, and the insider sees the species."
It should be said that jade lovers are very concerned about the jade germplasm. Buying a glass of jade is a lot of people's ideas. Differentiating between ice and glass, most people look at transparency. Compared with ice jadeite, the glassy jadeite crystal grains are finer and more transparent, while the ice type jadeite is also very good in water and very transparent. In this case, facing an emerald, relying solely on transparency to distinguish between glass or ice is not easy for many people. In the case where it is impossible to distinguish between glass and ice, there is a simple way to judge it - whether it is marked by fluorescing.
The fluorescing, that is, the kind of glass with fluorescence; it is very transparent but not strong, it is ice. Jade has a thick problem, the thinner it will be, the more transparent it is. This is especially important for ice and glass. Some jade merchants often make the ice jadeite very thin, and then use K gold inlay, reflective surface to the bottom, so that the ice jade looks like glass. Therefore, it is judged that the ice species and the glass species must be based on a certain thickness.
Is glass more valuable than ice? The reason why many jade lovers are very concerned about ice and glass, one of the main reasons is that glass is worth more than ice. In fact, it is generally incorrect to assume that the value of glass species must be higher than that of ice. For example, pure white glass, the most expensive flower is about tens of thousands of dollars, and the full bloom of ice, if the shape is full and full, one can sell for several million yuan. Therefore, it is important to fully understand the value composition of jadeite, rather than distinguishing between ice and glass. Under what circumstances is it important to distinguish between ice and glass? That is the pure white variety in jade. Due to the same size of pure white ice and glass, the price difference is very large, at least 10 times, so it must be clearly distinguished. In practice, many collectors bought the flower pieces of white ice as glass, and spent thousands of dollars. They also felt that it was very cheap, that is, there was no clear distinction.
Glass and ice are very transparent, and the particles, impurities and splitting are easy to see and even clear. Impurities are of course a disadvantage, but they cannot be completely seen for jade. Because jade is not a diamond. As a single crystal mineral, diamonds are not allowed to have impurities visible to the naked eye. Jadeite is a combination of various minerals, and there are bound to be various structural and crystal changes. Most jadeites are opaque, while ice types and glass types are fine and clean. You can see the structure inside. If you don't know how to do it, you will think that such jadeite is not perfect. In fact, it is the defect that contrasts with the exquisite jade texture. A high quality jade has a bit of impurities and is generally not a big problem. In fact, the top jadeite is not without any embarrassment. Looking at a jade, it is not a matter of picking, but looking at a few big aspects, seeing the most rare places - good species, lustre, good shape, This is very rare. Just because of the impurities, the good jade is missing, it is a shortcoming.
