Can a white mist flashlight shine into the white mist on the skin shell of the jadeite rough?

Hello, first of all, the skin shell of jadeite is divided into many kinds, not every skin shell can be illuminated, some skin shells are nothing to perform, it can also be high-quality, as for the skin shell you said has white fog, the first thing is to look at the field, then look at the characteristics of the shell, and finally it is irradiated with jewelry flashlight, there is a lot of white fog, if the skin is thin, it can shine into the fog, and the skin thickness does not shine into the fog, this thing should be comprehensive, not to say that it is good to enter the light, and it is not good to shine into it.

Judging the rough by looking at the "fog" is one of the important means.

Fog"It refers to a layer of foggy opaque material that exists between the outer weathered shell and the inner jadeite, which is actually the result of the degeneration of jadeite minerals. In short, "fog" refers to a semi-oxidized and slightly weathered layer of jadeite between the skin of the jadeite and the inside or flesh of the jadeite.

Turn on the light to see if there is white fog in the rough stone on the leather shell.

The fog is thick and thin, and the colors are white, yellow, black, and red.

Look at the white fog: after the outer skin is ground off, the white inside is revealed, like the white garlic skin covered on the color, the color of the stone in this fog is light, once the fog is removed, the color is thick. The white mist is generally underneath the white salt sand and the white python.

Yellow fog: If the material has moldy pine flowers, remove the pine flowers, the fog is very yellow, wipe off the fog, the color will be blue, and the yellow flavor is insufficient. There are also pine flowers that can't see the color when they are rubbed, and it is the fog that separates the color, and then they are exposed.

Black fog: If the fog is thick, the bottom is gray; The black fog has high green and low colors. Black fog loves to run gray, so many people are reluctant to gamble.

Red fog: Generally speaking, there are many gray bottoms, red fog loves to run skin, fog is most afraid of running to the skin, ten or nine gray running skins, and there are very few gamblers.

Look at the cracks inside the jade. Irradiating the internal cracks of the jade, the light source of the flashlight is shifted to observe the dark reaction of the internal light source of the jade, or there is an uneven reaction to the change of refracted light. Take a look at the internal structure and lines of jade.

Only by irradiating the jadeite at a 45-degree angle can we clearly observe the internal structure of the jadeite and the orientation of the stone pattern.

Look at the cracks and look at the impurities. Hold the flashlight close to the surface of the jade to translate and observe if there are black spots inside, and the impurities often appear as black hair. After glue is injected, there is a gap between the jade crystal and the dye, and cobwebs may appear when irradiated by a flashlight, or the jade may break.

The correct way to use the flashlight is to tilt the flashlight 45 degrees to 70 degrees to illuminate, so that you can see the internal structure of the jadeite more clearly.

Direct radiation refers to the flashlight perpendicular 90 degrees to irradiate the jadeite rough, if it is a natural jadeite, it must have good light transmittance, the flashlight is close to the surface of the jadeite to observe whether the light can penetrate, if it can be easily penetrated, it is likely to be a natural jadeite. At the same time, you can also pan the flashlight to observe the internal structure of the jadeite.

Multiple points irradiation, according to which the fineness of Hetian jade core shed stone and the thickness of the particles can be identified. Look at impurities; Taking Hetian empty jade as an example, the jade flashlight is used to close the back of Hetian jade, and then slowly translated, so as to identify whether there are impurities in the structure of Hetian jade, and when there are impurities, dark spots will appear inside Hetian jade.
