Identification method of crystal glasses, identification method of crystal glasses

To distinguish the authenticity of crystal glasses, the method is as follows:

1) See: natural crystal in the formation process, often affected by the environment always contains some impurities, when observing the sun, you can see a faint uniform fine horizontal stripe or catkins like substance. The fake crystal is mostly smelted with residual crystal slag and glass slag, polished and colored, and there are no uniform stripes and catkins.

2) Tongue licking: Even on dog days in the hot summer, licking the surface of the natural crystal with your tongue gives you a cold and cool feeling. Fake crystals, there is no cooling feeling.

3) Illumination: Natural crystal is placed vertically in the sun, no matter which angle you look at, it can emit a beautiful brilliance. Fake crystals cannot.

4) Hardness: Natural crystal has high hardness, and it will not leave traces if you gently scratch it on the jewelry with crushed stone; If there are streaks, it is a fake crystal.

5) Check with a polarizer: Rotate 360 degrees under the polarizer and have four bright and four dark changes are natural crystals, and those that do not change are fake crystals.

6) Check with dichroism: natural amethyst has dichroism, and false crystal has no dichroism.

7) Check with a magnifying glass: Check with a ten-fold magnifying glass under transmitted light, and the bubbles that can be found can basically be determined as false crystals.

8) Check with a hair strand: Put the crystal on a hair strand, and the human eye can see the double shadow of the hair through the crystal, it is a natural crystal, mainly because the crystal has birefringence.

9) Detection with thermal conductivity meter: adjust the thermal conductivity meter to 4 grids of green to test gemstones, natural crystals can rise to 2 grids of yellow, while false crystals do not rise, when the area is large, it rises to one grid of yellow.

Natural crystal identification to see the authenticity. The main methods are: looking, touching, trying, knocking, comparing, wearing, seeing, and measuring.

Look, taking the lens as an example, the difference between the crystal and the glass is mainly to see whether there are scratch lines on the surface of the lens. The crystal lens has high hardness, and the general surface is smooth without scratch lines; Glass lenses are softer, and the lenses are hairy, and scratches can be seen on the mirror surface against the light.

To the touch, natural crystal lenses are always cold to the touch, and fake crystal lenses will have a sense of temperature for a long time.

Try, to the lens, natural crystal lens moisture disappears quickly, fake crystal lens moisture disappears slowly.

Knock, gently collide the two lenses, the sound of natural crystal lenses is crisp and pleasant, and the sound of fake crystal lenses is dull.

Comparison, that is, comparison, mainly true and false comparison, superior and inferior comparison, ** comparison, etc.

Wear, crystal glasses are very comfortable to wear and have a cool feeling.

Look, natural crystals look warm in color, and fake crystals look cold.

The simplest and most scientific test is to send it to a formal testing agency to issue a test certificate. The most accurate, the most effective, the most authoritative.

The last penny is worth the money Natural crystals are non-renewable resources, and good crystals are sold by the gram and will not be so cheap.

Summary. Spectacle lenses made of natural crystal appear speckled when sunlight is observed, while artificial crystal spectacle lenses are only neat and single-positioned.

1. The history of crystal glasses: As an optical material, the biggest advantage of crystal is that it is hard, and the lenses made are not easy to wear. **Crystal glasses are not easy to absorb fog in the air, and the lenses are generally cooler, while artificial crystal glasses do not have these characteristics, and this method can be used to identify crystal glasses.

Natural crystal has high hardness, even if it is lightly scratched with glass, it will not leave marks, while inferior products will leave traces, and this is also a big difference between natural crystal and artificial crystal.

2. If you do it yourself. The best way to do this is to see if there is cotton inside the lens crystal. Another way is to place the lenses at a 45-degree angle to the light.

Observe the lenses for water streaks. Whether there are water ripples in natural lenses is related to the curvature of the lens. Generally, 500-curved lenses are free of water lines.

It is the most accurate identification method. It is to use an infrared spectrometer analyzer.

3. Crystal glasses are divided into natural crystal stone glasses and synthetic crystal glasses. Natural crystal stones have experienced hundreds of millions of years, absorbing the essence of heaven and earth, and itself has a strong energy field. It can be eye-catching. It has a good effect on eye discomfort when looking at mobile phones often.

I'm glad to answer for you, if you're satisfied with me, please give me a thumbs up, thank you

How to distinguish the real from the fake with natural crystal glasses.

Spectacle lenses made of natural crystal appear speckled when sunlight is observed, while artificial crystal spectacle lenses are only neat and single-positioned.

Summary. The method of distinguishing the authenticity of crystal glasses: 1. Put a hair on the crystal glasses, and the human eye can see the double shadow of the hair through the crystal, which is a natural crystal, mainly because the crystal has birefringent properties.

Another characteristic of natural crystal and artificial crystal is the luster of crystal, the surface of natural crystal shows grease luster, and the surface of artificial crystal presents glass luster. 2. Because the crystal is cold in the hot summer, so wearing crystal glasses will make people feel clear, especially spiritual, and will make people eliminate fatigue, if you stay up late at night and your eyes are dry and tired, the next day you wear crystal glasses for more than an hour, you will feel that your eye sockets are moist, just like walking in the woods after the rain, which is particularly comfortable. 3. Natural crystal is placed vertically in the sun, no matter which angle you look at, it can emit beautiful brilliance.

Fake crystals cannot. So, this method can also be applied to crystal eyes. 4. The unique structure of the crystal makes the strong light refracted, so wearing this kind of crystal glasses in the outdoor strong light or under the light will make people feel that the light is soft, not dazzling, and very eye-catching.

Crystal glasses are a type of high-end glasses that many people like, but there are also many fakes on the market. First of all, we can observe the appearance of crystal glasses. Real crystal glasses are usually dark blue in color, uniform in color, and free of bubbles and impurities.

If there are burrs, potholes, or particles on the surface of your glasses, it may be because the glasses are made of low-quality materials and the quality is uneven.

Secondly, the quality of crystal glasses needs to be judged by touch. Authentic crystal glasses are very lightweight, delicate in texture, and very smooth to the touch. If you find that the surface of the glasses is particularly rough or feels heavy, these are one of the common phenomena of fakes, and you need to be careful.

Finally, the authenticity can be identified by light. Put the crystal glasses on a piece of positive white paper to lift the socks, with a mobile phone flashlight downward, if you can see a clear "X" shape, it means that the crystal texture is good, yes. If you can't see the "X" shape, or if there is an iridescence on the surface of the glasses, then there is a good chance that the glasses are fake.

In short, when buying crystal glasses, you must carefully distinguish the authenticity, so as not to spend a lot of money and not get the matching glasses. If you have a better understanding of the material and the process of making crystal glasses, it will be easier to spot fakes.

Summary. The identification method of crystal glasses is as follows:1

Visual identification. Stone glasses are made of natural crystal, and there are impurities or fine lines in the lenses due to the quality of the crystal. 2.

Haptic identification. Licking the lenses with your tongue, the cooler ones indicate that they are real stone glasses. 3.

Hardness identification. If you scratch the surface of the stone mirror with glass, there will be no marks on its surface if you scrape it with gravel.

The identification method of crystal glasses is as follows:1Meat judgment book no eye identification.
