Ask for the authenticity of jadeite, as well as the difference between water foam and jadeite! 5

The first method: tapping. Hanging the jadeite with a thin line, striking it with a confirmed natural jadeite, agate rod or other harder utensils, the sound of natural jadeite is clearer and more melodious, the echo is far away, the more delicate the germplasm, the clearer the sound, and the artificially treated jadeite has a dull sound, abruptly stopped, and there is no echo.

The second method: weighing. The average density of jadeite is , generally more dense than similar jade, and weight is sometimes very effective in determining authenticity.

There is a kind of jade on the market called water foam (water foam jade), which is very similar to high-grade ice jadeite, and it is twin brothers with jadeite, that is to say, while producing jadeite, it will inevitably produce water foam. However, the average density of water foam is only, and water foam of the same volume and size is much lighter than jadeite, and its economic value is much smaller.

The third method: slippery. The surface of natural jadeite is smooth, and the surface of some coated jadeite is astringent and not smooth, which can be distinguished from the slippery feeling.

The fourth method: cooling. Generally, it is also for coating, glue injection, etc., and the natural cooling feeling is more obvious.

The fifth method: fracture observation. Fracture refers to the unpolished fracture surface of jade, even if it is a finished product, sometimes you will see tiny fracture surfaces, jadeite fractures are granular, nephrite jade fractures are flat, quartz jade, glass fractures are shell-shaped.

I also studied this paragraph!! I also have to see and learn more, and I can slowly distinguish clearly, I have a few pure natural A jadeite, if you don't dislike it, go to my space antique album or blog post to see. This is one of them, pure natural a goods jade pretty color pendant, bat, mouse, ingots, ruyi.

The most reliable way to do this is to take it to the testing institute for identification.

<>1. The different structure is one of the main differences between foam jade and jadeite, and the crystal particle structure of foam jade is fibrous or granular structure. Jadeite, on the other hand, has delicate flesh and very fine crystal particles, which are arranged in tiny columnar or fibrous structures.

2. In addition, the difference in jadeite is also the difference between foam jade and jadeite, jadeite is one of the characteristics of jadeite, is a unique phenomenon of jadeite, can be used as the basis for judging jadeite. Although the appearance of foam jade is similar to that of jadeite, it will not show emerald.

3. From the point of view of the gloss of foam jade and jadeite, the refractive index of foam jade, and the refractive index of jadeite. Therefore, the refractive index of jadeite is stronger, and the glass luster will be more dazzling and bright, while the reflective luster of foam jade will be relatively dim.
