1, look at the luster, the real jade bracelet is glass luster, and the fake jade bracelet is mostly waxy, with poor luminosity and smoothness. The simple identification of jade bracelets can be observed with the naked eye, first look at the luster of natural light.
2. Look at the luster of the jade bracelet. The natural A jade bracelet has a smooth surface, and the jadeite with good polishing and dense texture can present bright glass luster. Due to the influence of intergranular gap and orange peel effect, the luster of rough jade is weak, ranging from sub-glass luster to oily luster.
3, how to identify the jade bracelet to see the color of the authentic jade bracelet is very pure, it has colored roots, you can see it clearly. There is no color root inside the fake jade bracelet, and the color seems to float on the surface, and there is no transition or obvious transition from the inside to the watch.
4. The density, hardness, light transmittance, refractive index and polarization of jade bracelets can be analyzed by instruments, and its accuracy is particularly high, which is beyond the reach of manual identification. However, the price of machine identification is high, and manual identification is generally used to judge the authenticity of jade bracelets.
5. Share three ways to identify jade bracelets. Most jade bracelets are mainly green. Jade bracelet has high hardness, certain anti-collision function and relatively simple maintenance. Transparent without impurities, moist and shiny are its main characteristics. Most jade bracelets are mainly green.
How to treat B jade bracelet under the light? B what does the jade bracelet look like in the light?
Seeing jadeite with purple light means observing jadeite under purple light, because natural jadeite has no fluorescence reaction, and many B-grade jadeites, that is, jadeites with fillers such as epoxy resin, will fluoresce under purple light irradiation.
Looking at the structure in the light, the structure of goods A is clear, the structure of goods B is fuzzy, and the cotton inside also gives people a sense of divergence. For red and yellow jadeite, goods B and C give people the impression that the color is unnatural, the color edge often diverges, the color floats, and the color root is invisible or not obvious.
Color; Looking at the jadeite of B goods according to the light, we can see that there are many potholes on the surface of B goods, and the color is not bright and unnatural; C jadeite can see the color distribution along the crack under the light, which looks like capillaries.

How to turn on the light and see how to hold a flashlight with a jade bracelet.
Tilt the flashlight 45 degrees to 70 degrees and polish it, so you can see the internal structure of jadeite more clearly. Crack it first. When choosing jadeite, we should pay attention to whether there are "cracks and growth lines" in jadeite. Don't use too strong light when looking at cracks. Make sure that jadeite with cracks has low value. It is not recommended to start.
Cracks: You can also use a flashlight to check the cracks. Tilt the flashlight by 45 to 70 to polish the jadeite, so that you can see more clearly whether there are cracks in the jadeite. There are few cracks in real jadeite, but there are no cracks in fake jadeite.
It is an important purpose to identify the jade bracelet with a flashlight, shine it directly on the jade surface, slowly attach a 90-degree flashlight, check the aperture and judge the light transmittance inside the jade.
You can see the fluorescence of jade bracelets with ultraviolet rays. When you irradiate the jade bracelet with an ultraviolet flashlight, if the jade is treated by chemical methods such as pickling, glue injection and dyeing, the jade bracelet will have a fluorescent reaction.
There are bright flashlights specially used to look at jewelry in the market. Strong flashlight is the most commonly used tool when looking at jadeite original stone, because it can observe jadeite more clearly. Looking at the original stone with a flashlight is mainly to better observe the defects and internal structure of the stone such as water, cracks and dirt.
Everyday jade bracelets and other jade ornaments are all from the original jade stone, and the quality of the original jade stone also has a certain identification method, and knowing how to use a strong flashlight is one of the very important skills. Three uses of strong light flashlight are introduced.
