Buying jade on the Internet, as a buyer, is nothing more than two channels of understanding: pictures and text descriptions. According to pictures and texts, how to judge the quality of online jade?
The following five methods hope to bring you some practical experience.
First look at the art photo. These photos are basically taken in professional studios, usually with a beautiful background, only very light shadows, and the light is very soft. The photo can cover up the shortcomings of the real thing, such as yellow dirty and light lines, making the jewelry look delicate and the color is like spring water.
The second look plus lighting. This kind of photo does not have too much background and strong light and shadow effects, so it is more concealed. The first is the background reference. If the background is a hand or other common things, we can judge the degree of polarization of the jade according to the degree of polarization of the background. In general, the addition of white light can improve the transparency of jadeite, cover up small cracks and dirty spots, make the dark color become brighter, and make the gray ground brighter; adding yellow light can make the jade texture look more even and make the light color become richer.
The third look at the PS photo. This kind of photo is used to process the image later. If the light source is strong, it will generally reflect on the light side, a little overexposed. The PS photo is different, it is the artificial addition of light to the photo later, usually to make the gray ground brighter.
The fourth look at the text description of the phenomenon of boasting water. All kinds of beans are said to be ice, and ice is said to be glass. In fact, about planting water, you do not have to refer to the seller's statement, the reference picture is the most important. As long as it is not an art photo, whether it is plus or not, it can be judged by the shadow relationship with the background. For example, a bracelet, holding a photo under natural light with a hand, the shadow of the finger is not printed on the inside of the bracelet in the foreground, or the shadow is not clear, and the seller is marked with ice or even higher, which is obviously not up to . In fact, in reality, as a buyer, don't be too obsessed with what kind of water is in the end, but depends on its comprehensive performance.
The fifth look at the embarrassing problem of text description. In general, the lines, cracks, dirt, sputum, stone ribs, the knife in the carving, the wrong knife and the polishing are not good, and even the shape is not neat, the image is not normal, can be called ç‘•ç–µ. It is necessary to treat the jadeite of the emerald correctly. On the one hand, the seller always declares that “there is no sky and no jadeâ€, although there are all kinds of cracks in the original stone, but the processed jade will generally try to avoid the crack. On the other hand, it is necessary to treat the impact of ç‘•ç–µ on the value of jade. Generally speaking, the inner side has a small influence on the value, the outer side has a large influence; the transverse crack has a small influence, the longitudinal crack has a large influence; the edge dirty influence is small, and the frontal dirty influence is large; the influence of the knife is small, and the influence of the defect is large.
The value of jade is not determined solely by the water. The water is good, the land is not clean and not worth the money, the ground is clean, the size is too small and not worth the money, the size is right, there is obvious value of the crack, there is no crack, the water is too poor or worthless. Therefore, when shopping online jade, you should balance and choose the baby that suits you.
