In the past two days, several Cuiyou have asked questions about the old and new species of jade, and everyone has some misunderstandings about the cultivation of old jade. I believe that everyone has heard of the old pits of jade or the old jade, all said that its germplasm is fine, the water head is good, then what is the old pit species jade? At the same time, there are several misunderstandings that Cuiyou must pay attention to! What is the old pit kind jade The old pit is jade, the jadeite is commonly known as the "old pit glass", usually with glass luster, its texture is delicate and pure, the color is pure, bright, rich and even emerald green: the old pit is jade with fiber intertwined crystal The structure is mainly composed, and the hard main grain is very fine; the old pit type jadeite is translucent or transparent under light irradiation, and is the top or the best in jadeite. Of course, even the well-balanced old pits have relatively high quality, some have higher transparency, some have less transparency, so the value is different, but in any case it is more attractive jade varieties, often used to make high-end For jewelry. The difference between the old pit jade and the new pit jade The old pit jade and the new pit jade are different from the growing age or the internal structure. From the internal structure of the jade, the internal structure of the old pit jade is dense, and the composed mineral crystal particles are closely combined, and the new The internal structure of the jadeite jade is relatively dense, and the internal crystal particles are not so tightly integrated. Misunderstanding First, the old pit species, the new pit species is the old and new Jade has primary and secondary mines. The formation of primary ore is due to the geological movement of mountainous geology. Most of the jadeite produced in the original ore is not fine, and it is dry and the head is insufficient. The original deposits have some ore of different quality. After the flow of water, some of the poor quality, impure jade will be naturally sorted, eliminated, and finally the jade that remains in the riverbed is washed and soaked by the river for a long time. The minerals are uniform in color, with sufficient water head, texture and structure. In fact, according to the geological point of view, the geological ages they formed in the underground are the same, only the different years of mining jade. "You can't simply judge the age based on the words 'new pits' and 'old pits'. Some new pits are formed earlier than the old pits. Second, the old pit species are glass species, ice species The most recognized in the market is the old pit glass, which is the top or best of the jade jade market. The glass type has a glass luster, and its texture is fine and pure and flawless. The color is pure, bright, rich and uniform. The emerald green pits are translucent or transparent under the illumination of light. The old emperor of the emerald dynasty thinks that the ice jade is lighter than the glass, and the inside has visible particles, which are second to none, but the high-ice jade can also be called high-grade. Glass species and ice species belong to the typical old pit species. This is determined by its formation conditions. After the scouring and soaking of the flowing water, it can leave such delicate products, but the old pits do not necessarily reach the glass species. The level of ice, there will still be a lot of poor quality 'missing fish'. Third, the old pit, the new pit and the old pit species, new pit species In fact, these two groups are different concepts and are easily confused. The jadeite's primary mine is called a new pit, and the secondary mine formed by natural forces such as river water is often called the old pit. The jadeite secondary mine (old pit) is often produced with high-quality jade. These high-quality jadeites have outer skin, fine texture, small crystal particles, water head (good transparency) and heavy specific gravity, so they are called old pits. Relatively speaking, the original ore (new pit) texture is generally the majority, the texture is rough, the water head is poor, the proportion is also slightly light, so it is called the new pit species. In fact, it is understood that the original mine (new pit) will also have high-quality jadeite, although the number is very small, it can also be called the old pit species. Since the old pit has almost no output at present, many new pits on the market come from the new pit. Therefore, the old pit and the new pit are the concept of geography and the distribution of geology and minerals, while the new pit species and the old pit species are the concept of jade quality. As long as it is high-quality, high-transparency, crystallized and delicate jade, it is the old pit kind of jade. The old pit jade is also the most worthy of attention of collectors.
