Chinese people like jade, especially like jade and Hetian jade. If they like it, they will study it and ponder it, and want to have an in-depth understanding of it. People's research found that it is very difficult to thoroughly understand jade, so there is a saying that "the god is difficult to break the inch jade", "the gold has the price of jade is priceless", the former refers to the "gambling stone" of jade raw materials. The unpredictability of the latter, the latter refers more to the difficulty in estimating the value of jade assessment.
Indeed, the evaluation of jade is very difficult, but it is not impossible to start. People have learned some experiences in long-term practice, and different people have come up with different evaluation methods. For the evaluation of jade, there are “4C, 2T, 1V†methods in the industry, which are evaluated from color, process, flaw, crack, species, texture and size. There are also “2C, 2T, 2S†methods, ie from color and texture. The water quality, transparency, texture, clarity, craftsmanship and quality are evaluated according to the national standard “Jadeite Gradingâ€. The standard is divided into green series, colorless series and other color series. These methods condense the wisdom of people after long-term practice.
In general, color, texture, transparency and clarity are essential elements for the evaluation of jadeite. According to the shape of jadeite, considering its craft and quality (such as jade ornaments, the proportion of craftsmanship is more important). In practice, it is necessary to fully consider that jadeite is a polycrystalline aggregate. Each evaluation factor does not exist in isolation. After each element is evaluated separately, it needs to be integrated together for an organic overall evaluation.
Let's take the jade bracelet as an example to briefly talk about the shortcut method of jade evaluation.
The color of jade is very rich, there are green, yellow, purple, etc. The most common is green, all kinds of shades, shades of green, combined with the color distribution, forming an ever-changing jade.
Only the green jade bracelet can be presented in a variety of colors, including green, green, green... and the green jade bracelet, the difference in color, transparency, texture and other factors, Its value impact is very obvious.
As shown above, the green and jade bracelet with good water color can be classified into the top collection series, with a value of over ten million. Its color is rich, the color is strong, the transparency is good, it reaches the ice to the glass, the texture is fine, and the interior is pure, no obvious viscera. From the four elements, the evaluation can reach the highest level and is perfect.
The above picture is a good green emerald bracelet, which is also a valuable collection worth more than one million. This jade bracelet is thick and translucent, which is usually said to be degenerate and delicate. According to the four elements, the evaluation is in the upper middle level, and the overall is perfect.
The beans in the picture above are full of green jade bracelets. Although the color is full, the crystal particles are obvious, the texture is slightly thick, the color concentration is medium, the transparency is low, and the value is about several hundred thousand. The key element of this bracelet is the color, which is bright and has a certain concentration. If its color saturation is reduced, or even color cast, it is commonly referred to as apple green or bean green, then its value may be tens of thousands to thousands.
It can be seen that although the evaluation of jade is difficult, after analyzing and re-integrating the elements, it is still possible to find that its value can be followed. However, keep in mind that each element does not exist in isolation and requires an organic comprehensive evaluation. As long as continuous analysis is carried out, a suitable evaluation method for jade can be explored.
