Cracks in jade are a fatal defect, especially in jade bracelets. Cracks not only affect the overall appearance of jade, but also its practicality. When evaluating the value of jade, we must pay special attention to observing its cracks. Listen to what Cuixuan Yipin has to say! Cracks in jade can be divided into congenital cracks and acquired cracks. The former is formed under the influence of internal forces during the early formation process of jadeite. The latter is caused by human factors and can be divided into natural factors and human factors. On the one hand, there are cracks formed naturally by geological movements. On the other hand, the most common is cracks that appear in jade during the mining and transportation process. We need some construction machinery to mine jade, so when digging jade, the construction machinery may not know the location of the jade, so the force point may directly hit the surface of the jade and cause cracks. If the crack is located in an important part of the jade, it may directly affect the overall value of the jade. Cracks are a fatal flaw, and the price of jade is affected by these cracks. Huika mine produces many high-quality jades. Although the raw stones have cracks, the cracks are neat and not broken. Therefore, as long as the cracks are regular and scientifically cut, high-quality bracelets and other finished products can still be produced. Whether it is primary crack or secondary crack, it is the result of internal damage to the jade. Therefore, under strong light, we can see cracks, and when we touch the surface of the jade with our hands, there will be a foreign body sensation. Cracks are fatal damage to jade. The value of jade with cracks is greatly reduced, especially high-end jade. Therefore, the number and length of cracks are inversely proportional to the value of jadeite. Furthermore, closed fissures are much less harmful than open fissures. Depending on the location and length, jade cracks are divided into no cracks, micro cracks, difficult to see cracks, visible cracks, easily visible cracks and obvious cracks. Jade without cracks naturally has the highest value. When purchasing jade, you should first check whether there are cracks. If there are cracks, the buyer can judge the price or decide on the choice based on the size and number of cracks. If there are cracks that affect the hardness and service life, it cannot be purchased. When purchasing jadeite, you can first use a flashlight to observe the cracks, paying special attention to distinguishing the "cracks" and "growth lines" of jadeite. Do not use too strong light when looking at cracks. Secondly, using a flashlight can help you observe the internal texture structure of the raw stone and judge the quality of the raw stone. Cracks not only affect the beauty of jade, but also its strength. The impact of cracks on jade is fatal. In mild cases, it will leave hidden dangers of jade breakage, and in severe cases, it will break directly. fruit feicuibbs1 fcgc60 |
