What are the ways to distinguish jewelry and jade?

Gemstones mainly include diamonds, night pearls, opals, emeralds, rubies, sapphires, etc., which are expensive, and man-made gems are beautifully made, but they are fake gemstones. Generally speaking, fake gemstones can be divided into four categories, one is plastic and glass imitations; the second is to use stones similar to gemstones to bond and imitate; the third is to use chemical synthetics to counterfeit diamonds (such as alumina); The fourth is to add pigments to transparent ore and pass off as gemstones. The following Beijing stone renovation company will introduce some identification methods for you.

1. Appearance: real gemstones have clear and natural lines, clouds, and crystal characteristics; Fake gemstones have no natural textures, no clouds, and no crystalline features.

2. Heat transfer: real gemstones are slow to heat after being heated, and they feel cool when touched by hand; Fake gemstones transfer heat quickly after being heated, and they feel hot when touched by hand.

3. Observe with a magnifying glass: there are curved swirl flow patterns on the surface and inside of fake gemstones, round or oval bubbles, and traces of fracture casting can be seen, while real gems do not have this phenomenon.

4. Hardness: The hardness of diamonds is 10 degrees, rubies and sapphires are 9 degrees, and there are gemstones with lower hardness. In the part that does not affect the appearance, use a diamond to scratch the gemstone, if it can leave scratches, it is a real diamond; You can also scratch the gemstone on the topaz (hardness 8), if it leaves a trace, it is a real gemstone.

5. Color: red, blue, green, orange, purple, yellow and a variety of colors. Such as rubies, pigeon's blood red is the best, natural gemstones with a magnifying glass, there are inclusions and cracks; Artificial gemstones, on the other hand, are particularly pure, free of impurities, bubbles, and have traces of "doing".

6. Polychromacy: Real gemstones have polychromacy. For example, a sapphire is blue when viewed from the bottom of the sun, and blue-green when viewed sideways; Fake gemstones do not have this characteristic.

7. Fire roasting: real gems will not be broken in fire roasting; Fake gemstones may be fakes when they are roasted in a fire and will crack when the temperature rises to 90 degrees Celsius.

Summary. Dear, hello, I'm glad to answer for you, you can check the gaps to identify the authenticity of jade, the real gaps are slightly translucent, the color is lighter, and the fake gaps have pigment deposition, and the color is darker. You can also observe in the light, and when you observe in the light, you can really see asbestos, cracks and other defects, and the fake interior is very clean, pure and flawless.

It is also possible to do a fluorescence test, which really does not emit light under ultraviolet light.

How to identify jade.

Kiss, the identification method is as follows: 1. Check the gaps. To identify the authenticity of jade, you can look at its crevices.

Take the jade to a brightly lit place and observe it with a magnifying glass, the real gap is slightly translucent, and the color is lighter, and the fake gap has pigment deposition and is darker. 2. Observe in the light. To identify the authenticity of jade, you can also observe it in the light.

If you take the jade to a brightly lit place and observe it in the light, the real jade can be seen to have asbestos, cracks and other defects, while the inside of the fake jade looks very clean and pure and flawless. 3. Fluorescence test. To identify the authenticity of jade, fluorescence testing can also be carried out.

Take the jade to the ultraviolet rays and observe, the real jade basically does not shine under the ultraviolet rays, or emits a small amount of fluorescence, and the fake jade is injected with glue, and the whole emits bright light.

Is there a number I can check if there is a number?

Did you check the identification certificate?

If it can be checked, it means that the jade certificate is genuine. Due to the different materials of the judging materials, the evaluation information that needs to be displayed will also enjoy a wide variety of different evaluation institutions, and the enrichment of the judging institutions is different, so in this regard, the appraisal report of jewelry and jade has never had a single-minded consolidated format.

Check the gapsHow to identify jade to identify the authenticity of jade, you can check its gaps. Take the jade to a bright place and look at it with a magnifying glass. The true crevices are slightly transparent and lighter in color, and the false crevices are pigmented and darker in color.

2.Observe how to identify jade under the light to identify the authenticity of jade, and you can also observe it under the light. Take the jade to a bright place and observe it under the light.

Real jade can be seen with asbestos, cracks and other flaws, while the inside of fake jade is very clean and pure. 3.Fluorescence test how to identify jade to identify the authenticity of jade, you can also perform fluorescence testing.

Take the jade to the ultraviolet light and look at it. True jadeite does not emit light at all under ultraviolet light, or fluoresces a little. The whole of the fake jade glows brightly after being bonded.

Don't think about learning it yourself, because jade contains a lot of kinds, each learning takes a lot of time, and it costs a lot of money, and it is also very easy to get away, so don't learn these knowledge, you just need to spend some money to send it to the national formal testing agency for testing.

The identification of jade, there are professional and jade identification, there are professional and simple methods. We generally buy a UV flashlight to identify jade. If there is fluorescence, it is injected.

01 The identification of jade can be judged by looking at the color, touching, observing, and listening to the sound. Jade is a mineral, there are two kinds of jade: soft and hard, and the jade usually refers to nephrite. It is one of the most common pieces of jewelry.

The identification of jade can be judged by looking at the color, touching, observing, and listening to the sound. No matter what the color of natural jade is, its color is natural and looks very pure and natural, while dyed jade is often too strong and appears limited to float on the surface; Jade has the characteristics of luster and denser, and the density is relatively large, so real jade is often cold and lubricated to the touch; Real jade tends to have an orderly and natural internal structure, while fake jade may be accompanied by man-made traces; Tap on the jade, and you can hear the crisp and pleasant sound of the natural jade.

Its value does not depend entirely on the ingredients, and the most of the jadeite white jade is worthless. Just like people, every nation produces heroes.

1. Water droplet identification method.

It is to drop a drop of water on the jade, such as a dewdrop that does not disperse for a long time, the real jade, the water droplet quickly disappears is a fake and shoddy goods!

2. Touch method.

If the real jade is touched by hand, it will feel cold and lubricated.

Facing the jade to the light, such as sunlight and light, if the color is clear and evenly distributed, it is real jade.

4. Tongue licking.

The tip of the tongue licks the real jade with astringency, while the fake jade has no astringency Finally, if there is a condition, you should use a magnifying glass**, mainly whether there are cracks, and those without cracks are high-quality jade, and some are secondary, the more cracks, the lower the value.

Tibetan jade should first be carefully read and read more monographs on ancient jade, these academic works embody a wealth of knowledge.

Generally jade before the Han Dynasty is"Ancient jade", museums in the United States and Britain, as well as ancient jade collectors in Hong Kong and Taiwan, like to collect ancient jade from the Han Dynasty onwards.

In addition to directly taking the jade to a professional appraisal agency for identification, there are also the following household methods:

Clause. 1. You can take a flashlight to irradiate, if it has a relatively high light transmittance, it means that it is a relatively pure real jade.

Clause. Second, you can drop a drop of water on the jade, if the water is not flowing down in strands, it means that the probability of being true is relatively large.

Clause. 3. You can also directly tap the jade with your hands, if the sound is very crisp and pleasant after tapping, it means that it is true, if it is a very low and muffled sound, it means that it is fake.

Observe with a magnifying glass, mainly to see if there are cracks, and the value of cracks is greatly reduced.
