In the traditional Chinese concept, Hetian jade, which is made of tremolite, is only produced in Hetian, Xinjiang. In other places, even if it produces high-quality jade, it cannot be called real Hetian jade. This is the opinion of the veteran players in the narrow sense. Even some players only play Hetian jade seed material, and they are unwilling to pay attention to Hetian jade in other places.
Since the introduction of the new national standard for gemstones, the concept of Hetian jade has expanded widely. Any jade with a tremolite composition of 95% is called Hetian jade. Like gold, silver, copper and iron, it is a physical name. It is. Not only Xinjiang Hetian and Hetian jade, Qinghai Kunlun and Hetian jade, Guizhou Luodian and Hetian jade, Russia's Baikal, South Korea's Chuncheon and Hetian jade, and Liaoning's Xiuyan area also produce Hetian jade, which is produced in Xiuyan. Known as the old jade, the old jade is divided into two types of mountain materials and river mill jade. The identification of the national authority's gemstone identification department also belongs to Hetian jade, and issued an appraisal certificate.
Hemo jade is a kind of seed material. Its name originates from the tremolite jade seed produced by China's Xiuyan. It is named after its origin in the river or river bed near the river.
The hero does not ask the source, the jade is the key, don't be superstitious about what origin, this is the right way to play jade. Because of its delicate texture, oily and beautiful colors, He Moyu is a wonderful flower of Hetian Yuzhong, so it is deeply loved by Yuyou.
He Moyu is produced in the area of ​​Xiuyan in Anshan City, Liaoning Province. As the name suggests, He Moyu is a pebble-like jade that is rolled in the river. It is produced in the river or in the riverbed. It is a kind of seed jade. The stone is not the same. It is difficult to judge people without certain experience, because the outer stone skin of He Moyu is thicker, so it is also called Shi Baoyu. Moreover, not all river jade jade is a good jade, specifically depends on the content, texture, color, oiliness, shape, hardness, impurities, dirt and cracks of the amphibole, to judge the pros and cons.
The source of the material is in the Gushan Mountain, and the Lonely Mountain is from the south to the north. After the analysis of the wood and the sea city, people still habitually called the Limu River. The reason for this is that the exposed surface of the old jade mine has been weathered and broken into blocks, and it has been washed by the mountain torrents into the Baisha River outside the ditch. It is rolled together with the pebbles in the river and ground into pebbles. The size is different, and the size is several tens of tons. More than ten kilograms and several kilograms. The good material is more in the middle and upper reaches, in addition to the green river mill jade, there are Huang Baihe mill jade, are the fine products of the river mill jade. The analysis of Muhe mill is not cheap in Xiuyan, because the river is rich in oil and fine, the jade is very hard, and the Mohs hardness is 6.36-6.46, which is comparable to the narrow Hetian jade, and along with the river. The number of grinding jade is decreasing year by year. It is said that the output is only one percent of the generalized Hetian jade. The resources are very limited, and now the raw material river bed has been turned over several times, so people think that it also has a large appreciation space, especially The yellow river mill jade is even more expensive. In general, the same size of the river mill jade block size is more expensive, smaller will be cheaper. Mainly still look at the color, such as the river mill jade bracelet has a few thousand dollars, and there are tens of thousands of one, the price difference is very different, gold is valuable jade priceless. When looking at the color, the main thing is to look at the purity, color, delicate density, oiliness, shape and skin color of the river jade. It depends on the stone weight, the stone flower is not much, and there are not many. These factors will play a decisive role in its value and appreciation potential. In terms of color, He Moyu has yellowish white, dark green, and blue-gray. It is best for yellow and white, and is the best jade for carving crafts.
Need to remind the Yuyou people a special sentence: Daiyu and Xiuyan Laoyu and Hemoyu are two kinds of jade with different physical properties. The prices are also very different. Don't confuse them. Be careful when buying.
Xiuyan mainly produces a large amount of jadeite - the scientific name is serpentine jade, with high purity and transparency, glass luster, but the hardness is very low. With the utility knife, it can depict obvious traces and white powder, because the hardness of jade jade Generally in the range of 2.5-3.5, (with the increase of tremolite can be as large as 6), the refractive index of 1.56-1.57, the specific gravity of 2.44-2.80, the range of variation is large. The physicochemical properties are also unstable, and it is easy to fade. It belongs to the middle and low grade jade in jade, and has no collection value and appreciation potential.
The broad-based jade jade also includes Xinjiang jade jade, Gansu Jiuquan jade jade and so on. Please jade friends must pay attention to careful identification when purchasing, it is best to send an authoritative appraisal department for identification, do not buy jade as a river mill jade to buy, because the price difference is more than 100 times. In recent years, with the rising price of He Moyu, the use of Xiuyan serpentine jade to pretend that the artificial fake phenomenon of He Moyu is prevalent, and some high-tech counterfeiters represented by Henan and other places are also native to Xiuyan. Some people who provide raw materials have joined hands to commit crimes. Just like making fake Hetian jade seed materials, the use of old jade mountain materials by artificial synthesis and chemical treatment means artificially making stone skin on the surface of mountain materials to make false real, if you have not seen the real river mill The jade people are hard to distinguish clearly. Only those who have actually seen the river jade can distinguish between true and false.
