Fine Collection JadeThere were many key points in collecting fine jade.
From the point of view of authenticity, this was the basic skill of collecting, which was also the so-called "eyesight". If you explore it yourself, you might encounter many traps. You can obtain relevant knowledge by consulting others. To determine whether a person was reliable, one could look at the things they displayed. If they were mostly collections or items that were auctioned off, they were more reliable. If the merchants released a large number of so-called " collections," there was a high probability that they would sell fake goods.
As for the selection of items, if the collector had the concept of return on investment, he needed to choose carefully. It could be collected according to the era, such as "Ancient Jade of Tang Dynasty","Ancient Jade of Song Dynasty","Ancient Jade of Ming and Qing Dynasties", etc. It could also be collected according to the use, such as "Ancient Jade","Ancient Mountain", or according to specific objects, such as "China Jade Cong","China Jade Bi", etc. The collection of ancient jade should be based on the standards of fine workmanship, excellent quality, exquisite color and strange shape. Moreover, the return rate of different subjects was different. For example, the return rate of different subjects such as pearl strings, group ornaments, animal carvings, seals, ritual vessels, etc. would vary. The price of different jade would also vary greatly.
In the process of collecting, not only must one be able to identify and select fine jade, but one must also consider the subsequent value transformation. That is, to be able to successfully trade the rare and high-quality jade assets in the collection. At the same time, one must also know how to maintain the jade and keep it in good condition, because the jade that was properly maintained would become more moist and precious over time.
When choosing jade, from the characteristics of the jade itself, hardness, moisture, and clarity were important considerations. Hardness was more durable, moisture affected luster, and clarity made the jade more vivid. Hetian jade and jade were all high-quality jade. In terms of color, the purer and thicker the green jade was, the better it was. Hetian jade used suet white as the top grade, but it could not be judged by color alone. It was also necessary to appreciate the natural color and texture of the jade. One could distinguish between real and fake jade by looking, touching, and listening. They could see the lines and luster, touch the texture, and listen to the knocking sound.
