The fluorescence of jadeite can be irradiated with a violet lamp.
The jadeite will fluoresce under the violet light.
The edges of the jadeite are light blue fluffy lines.
-
It is impossible to see the fluorescence of the jadeite rough, because the jadeite rough is with a skin shell, and the fluorescence effect can only be seen when the stone skin is cut off and processed to a certain extent!

In the identification and testing of jewelry and jade, ultraviolet fluorescent lamps (or red lights) are often used to detect the fluorescence effect of various gemstones, and if there is a fluorescence effect, it means that the gemstone has been artificially treated, which is one of the important characteristics of identifying and evaluating gemstones.
The first collection of jadeite must be clear about three concepts, that is, "species, water, color", according to these three to judge whether jadeite has collection value. "Species" usually refers to the structure of jadeite, among which glass species and ice species are high-grade jadeite, which have collectible value.
water", that is, transparency, jadeite inside because of different crystals, and show different forms, some are as clear as water, some are transparent as ice, the water head is good, transparent jadeite is the best product; "Color" is the color of jadeite, in addition to green and red, jadeite also has purple, white, gray, yellow, black and other colors, different shades, different colors.

First of all, this fluorescence does not refer to the fluorescence produced by the excitation of an external high-energy beam due to glue injection. High-grade jadeite, due to its high transparency and delicate crystals, will produce an internal refraction of the light coming from the outside in its own body, resulting in fluorescence. To observe this phenomenon, I recommend that you turn on a light in a room where the light is not strong and observe it as a point light source.

The jadeite of the glass species has fluorescence, and the ice species also fluoresces if you look at it obliquely, and you can see that the jadeite only needs to touch more and see more

To see the fluorescence of the jadeite bracelet, you can use ultraviolet light, when the jadeite bracelet is irradiated with an ultraviolet light flashlight, if the jadeite is chemically treated by pickling, glue injection, dyeing, etc., the jadeite bracelet will have a fluorescent reaction.
Jadeite before closing fluorescence, fluorescence is an optical phenomenon, and then popularly said that a piece of jadeite through the refraction of light makes the whole piece of jadeite uneven, causing visual contrast to the human eye, the stronger the fluorescence, the more obvious the contrast.
In the identification and detection of jewelry and jade, ultraviolet fluorescent lamps (or red lights) are often used to detect the fluorescence effect of various gemstones.
In fact, the fluorescence of jadeite can be irradiated with purple light, and the treated jadeite will show obvious fluorescence reaction under the violet lamp, and natural jadeite has no fluorescence reaction. It can also be observed in natural light, and light blue fluffy lines can be seen on the edges or patterns of jadeite, which is not the case with natural jadeite.

1. Look at the jadeite bracelet of the fluorescent smile Zhiyuan light can use ultraviolet light or light, when the jadeite bracelet is irradiated with an ultraviolet light flashlight, if the jadeite is chemically treated by pickling, glue injection, dyeing, etc., the jadeite bracelet will have a fluorescent reaction.
2. Jadeite fluorescence, fluorescence is an optical phenomenon, and then in layman's terms, a piece of jadeite through the refraction of light makes the whole piece of jadeite uneven, causing visual contrast to the human eye, the stronger the fluorescence, the more obvious the contrast.
3. The fluorescence of jadeite can be identified by purple light, and the treated jadeite will have obvious fluorescence reaction under violet light. When jadeite is excited by external energy (ultraviolet rays, etc.), it produces a luminescence phenomenon, and the luminescence stops immediately after the excitation source is withdrawn, and this luminescence phenomenon is called fluorescence.
4. Radian, fluorescence depends on the refraction of the light touching line, so the performance of fluorescence is also affected by the shape, angle and radian of the jadeite itself. Therefore, the pendant will carve some spherical surfaces on the edges to highlight the fluorescent effect.
5. Fluorescent jadeite, through the refraction of light, the visual contrast caused to the human eye, jadeite looks uneven, and there will be a hazy, soft and faint light on the surface.

<>1. To see if the jadeite is sensitive and senhui has fluorescence, it can be irradiated with purple light, and some jadeite that has been optimized by glue injection and dyeing will be placed under the purple lamp, and there will be a fluorescence reaction that will be displayed in the light, while natural jadeite will not fluoresce.
2. In addition, to see if the jadeite has fluorescent night, you can observe it under the natural late response light, and the edge of the jadeite or the concave part of the pattern will appear to be light blue fluffy thin lines, while natural jadeite does not have this characteristic.
3. Jadeite can also be soaked in boiling water to check whether there is fluorescence, most of the fluorescent jadeite will be dyed or injected with glue, this jadeite soaked in boiling water for a period of time, there will be decolorization or degumming.
