One is to look at jade:
In other words, it is clear whether this jade is old or new. There is an oxidized jade skin on the surface of the old jade, commonly known as "patina". The skin like autumn pear is obviously different from the natural color of jade, but Xinyu is not. In addition, jade should be moist, meticulous, glossy as fat, touching the spring water of the soul, bright and simple. If rough, dry, dull, opaque and flawed.
The second is to look at jade works:
The so-called "work" includes two aspects. On the one hand, it refers to the process. Generally lifelike, small and exquisite, lively ancient jade is often the top grade. Because the master who made the craft at that time often spent a lot of time carving, there was no good material and it was not worthy of its craft. Judging from the subject matter of carving, ancient jade is a symbol of rank and power, and there are also many flower-and-bird figures in mythology. Such as dragons and phoenixes. Xinyu is generally auspicious. On the other hand, "Gong" can also refer to fencing, that is, to distinguish between true and false from fencing. The concave lines of ancient jade all intersect at two ends, and the line section is V-shaped, and the lines are tall and powerful. At the corner of the line, you should see burrs, which show signs of crossing and are sometimes broken. However, in modern motor production, the cross section of intaglio lines is U-shaped, and its lines are "in one go", so the production is often shoddy. The drilling of ancient jade should be a "horseshoe hole" that is not straight and round, or a "trunk perforation". There are steps in the middle of the perforation, and some small holes should have spirals, which is caused by poor hand tools. However, the electro-mechanical drill has a smooth hole wall because of its fast rotation speed.
The third is to look at Qin Yu:
People who have been buried in ancient jade for a long time will be influenced by the soil. Jade soaked by Qin gives people a mysterious and subtle aesthetic feeling, with soil erosion and rust on the surface and water solubility and Tao in the body. Seqin soil spots are naturally distributed, or patchy or blocky. However, the distribution of piano color of fake ancient jade is either dotted or linear, and the shade is very dim, and the color is "dead color" Most fakes have low hardness. After the above steps, if this jade is Hetian jade, the workers are old workers, and the color is good, there is no trace of counterfeiting, at least it is a real ancient jade, which has collection value.
Fourthly, shape recognition, texture recognition, dating and evaluation:
Determine what it is, which dynasty it belongs to, and what is its value? The first three steps ensure the opening of ancient jade, and the next four steps are discussed in detail. It doesn't matter if you can't decide at the moment. You can study it slowly and record the ancient jade in the description. The older you get, the more expensive it is. But there are many fakes, so be careful. As far as the shape of utensils is concerned, pots, statues and Buddha statues are the most expensive, followed by birds and animals, and then aquatic animals. As for the finished jade with good quality, good workmanship and ingenious conception, it has become priceless without pricing.
In short, we need to see more and study more. Of course, I have some perceptual knowledge about Gu Yuguang, but I can't guarantee to buy ancient jade at the right price. Before buying, you must also be familiar with and understand the market.
But this aspect is lacking by a large number of jade lovers, who seem to be at a loss. When to go to the auction house and when to go to the antique market to find bargains.
Auction: Good jade appears from time to time, and appraisers usually check it, but they always pay close attention to the information of each auction and often run. A little negligence, good things will pass you by. In addition, the source and variety of auction lots are very complicated, after all, there are few all-round appraisers, and the appearance and disputes of fakes are sometimes inevitable. Another disadvantage of auctioning "Amoy" ancient jade is that the auction price is usually higher than the antique market.
Antique market: It would be great if experts and friends who know the market can help, because they can often pick out valuable things from a group of obscure low-priced jadeites, and also find some fatal defects from the so-called good jadeites repeatedly recommended by buyers. Sometimes the store will repeatedly declare the cheap jade price and go to more than half.
