The dripping identification method wipes the upper facet of jadeite clean, and dips the end of toothpick with a drop of water on it, which will show the shape of dew on the real jadeite and will not spread. Moreover, the water droplets on the fake jade may spread or slide down immediately.

Identification by soaking in water. If the jade doesn't pass through the clear water, use a spotlight flashlight to take a photo. If there are bright circles on the edge of jadeite, it may be B grade jadeite, not natural jadeite. Jade B goods have high transparency in water, and you can see the internal lines and cream wax of jade if you look closely.

First, drop a drop of water on the jade surface. If the water drops form a dewdrop state on the surface of jadeite, it is really jadeite. On the contrary, if the water drops disappear or dissipate quickly, then this is a fake jade.

To identify jadeite by water drop method, we must first drop a drop of water on the surface of jadeite. The water drops on the surface of real jadeite will last for a long time, while the water drops on fake crystal will fall off easily.

What is the method to identify the water drops of jadeite?

First, drop a drop of water on the jade surface. If the water drops form a dewdrop state on the surface of jadeite, it is really jadeite. On the contrary, if the water drops disappear or dissipate quickly, then this is a fake jade.

Water drop identification method: observe a drop of water on jadeite jade with naked eyes. If the water drops are dewdrops and don't scatter, they are real jade. If the water drops disappear soon, it is not jade. Tongue licking method: licking jade with the tip of the tongue is real jade, and fake jade has no astringent feeling.

Identification of jade by water drop method. First, drop a drop of water on the surface of jade. The water drops on the surface of real jade will last for a long time, while the water drops on the fake crystal are easy to fall off.

To identify jadeite with water, you can drop a drop of water on the surface. The water droplets on the surface of natural jadeite will not disperse for a long time, and the water droplets on the surface of synthetic jadeite will be lost quickly.

Step 1: Make sure there is enough water in the cup, empty the electronic scale, tie the second safety buckle with thin thread and gently sink to the bottom. Step 2, gently lift the thin thread to let the safety buckle leave the bottom of the cup, but it does not surface.

Three methods to identify jadeite adulteration How to identify jadeite adulteration?

Finally, according to the density formula, see whether the density value meets the national standard jadeite fixed value range, if so, it is natural jadeite, if not, it is fake jadeite.

Divide the data recorded for the first time by the data recorded for the second time. If the data is between 30 and 36, it means that jadeite is real, because jadeite is between 30 and 36 grams per cubic centimeter.

Dip a toothpick or needle into water, and then drop a drop of water on the jade surface. The water drops on the surface of natural jadeite will not be dispersed in the form of dew for a long time, while the water drops on the surface of artificial jadeite will be lost quickly.

In this range, it can only be proved that it may be true. If the measured density is not at the edge of this area, it must be false. A glass of water can really tell the authenticity of jadeite.

It is more reliable to identify jadeite A goods by bubble method, but it has limitations. Because many jadeites injected with glue use dyes, they will emit dazzling white light under strong light. But this method can only identify whether jadeite is injected with glue. If you don't inject glue to polish, but use other fake means, then this method will fail.

Step 1: Make sure there is enough water in the cup, empty the electronic scale, tie the second safety buckle with thin thread and gently sink to the bottom. Step 2, gently lift the thin thread to let the safety buckle leave the bottom of the cup, but it does not surface.

How to distinguish true jadeite from false jadeite with water?

Tie the jade with silk thread (to prepare for the next measurement) Put the cup on the precision electronic scale and remember to reset it (because it is not a cup). Put the jade into the water cup and record the weight at this time.

To test the authenticity of jadeite with water, you can first put a transparent water cup filled with water on the electronic scale, and at the same time clear the data of the electronic scale. Then tie the jade with a string and slowly put it into the cup. After the jade sinks into the bottom of the cup, record the numbers on the electronic scale.

Dip a toothpick or needle into water, and then drop a drop of water on the jade surface. The water drops on the surface of natural jadeite will not be dispersed in the form of dew for a long time, while the water drops on the surface of artificial jadeite will be lost quickly.

With a glass of water, you can simply identify the authenticity of jadeite. In fact, you are using junior high school physics knowledge here. Density is equal to the weight divided by the volume, and the volume of water is used instead of the volume of jadeite, thus calculating the density. The density of jadeite is roughly between 8 and 3. If the density of jadeite is finally measured,

The identification method of jade bracelet with water is as follows. You can drop a drop of water on the surface of the jade bracelet. The structure of naturally formed jade bracelets is very dense, and the water drops will persist for a long time like dew, but the water drops of naturally formed jade bracelets will be lost quickly.

Identification by soaking in water. If the jade doesn't pass through the clear water, use a spotlight flashlight to take a photo. If there are bright circles on the edge of jadeite, it may be B grade jadeite, not natural jadeite. If the jade doesn't pass through the clear water, use a spotlight flashlight to take a photo. If there are bright circles on the edge of jadeite, it may be B grade jadeite, not natural jadeite.

How does jadeite distinguish between true and false?

According to the color, density, smoothness and convexity of the epidermis, we can roughly estimate the internal color of jadeite raw materials, the quality of water head, the quality of land, the old and tender types and the number of cracks.

Judging the authenticity of jadeite includes: listening to the sound, watching the color, watching the clarity, weighing and measuring the hardness. Listen to the sound: tap the jade, natural jade sounds crisp, fake jade is black and heavy.

Look at the luster. Swing the jade left and right in the sun, carefully observe the luster of the jade surface, and identify the authenticity of the jade. Natural jadeite has a good glass luster, but the luster is not very strong. Jade has a strong resin luster after artificial dyeing and glue injection. Fluorescence reaction.
