How to identify the authenticity of natural crystal stones?

How to identify the authenticity of natural crystal stones? We can start with the appearance. An easy way to do this is to observe the color and transparency of the crystal.

Genuine natural crystal stones usually have a clear and transparent appearance and are uniform in color. If the crystal looks cloudy or uneven in color, it may be an artificial crystal or a dyed crystal.

We can use temperature tests to distinguish the real from the fake. Natural crystal stones will have a certain temperature sense at the human body temperature, and there will be a cold feeling even when touched at room temperature. So, you can try to warm it up a little bit in the palm of your hand before touching it.

If you can feel the obvious coolness, there is a good chance that it is a real natural crystal stone.

Another simple but effective way to identify is by the hardness of the crystal. Natural crystals usually have a high hardness and can scratch glass or cardboard. You can take a hard object (such as a coin) and try to scratch the surface of the crystal, and if the surface of the crystal is not scratched or left obvious marks, then it is likely to be real.

Observing the internal structure of the crystal is also one of the important ways to distinguish the real from the fake. Natural crystal stones usually have a naturally occurring crystal structure, and irregular textures and bubbles can be seen inside it. Artificial crystals, or treated crystals, tend to show uniform lines and a bubble-free appearance.

If you're still unsure about your judgment, consider seeking professional help. Professional appraisers usually have the experience and equipment to give accurate and reliable results in identifying the authenticity of crystals.

By observing the appearance, temperature test, hardness test and observation of the internal structure, we can preliminarily identify the authenticity of natural crystal. If you want to be more accurate, it's best to consult a professional or use professional equipment for testing. Remember, it's also crucial to trust a reliable merchant when buying natural crystals.

Natural crystals can be distinguished by hardness, luster, and feel.

1. Hardness. Natural crystals can be distinguished by measuring hardness, natural crystals are formed for a long time, their internal structure is dense and hard, if they are carved on the surface with sharp knives, there is generally no change, and fake crystals are mostly made of glass, and they are easy to leave traces after carving.

2. Luster. The natural crystal surface is mostly glass luster or grease luster, which looks like a crystal clear feeling, and in the sun, you can see obvious reflection, and the false gloss is not high, and it looks too dull.

3. Hand feel. The texture of natural crystal is warm and delicate, it gives people a feeling of warmth in winter and cool in summer, and it has a strong feel and fast thermal conductivity, while the thermal conductivity of fake crystal is very poor, it is rough after touching, and even a little prickly feeling.

Origin of Crystal:

Crystals are mainly found in pegmatite or geodes, and crystal mines are found almost all over the world. Famous production areas include Mi in Brazil, Galenas and Djilas, Madagascar, Arkansas in the United States, Urals in Russia, and Myanmar.

China's crystal resources are abundant, and more than 25 provinces have crystal output. Jiangsu is the main production area of China's high-quality water crystal crystal, among which the East China Sea crystal is the most famous, known as the "crystal capital of China".

Donghai County, belonging to Lianyungang City, Jiangsu Province, is located in the northeast of Jiangsu Province, bordering Haizhou District of Lianyungang City in the east, Maling Mountain in the west, Shuyang County and Guanyun County in the south, and Ganyu District of Lianyungang City along the Xinshu River in the northeast.

In addition, Hainan, Sichuan and Xinjiang are also the production areas of high-quality crystal.

The hardness of natural crystal can be identified from the hardness, luster and thermal conductivity, the hardness of natural crystal can reach, the thermal conductivity is very fast, the feel is very strong, it is greasy or glass luster, and the texture is warm and delicate. The hardness of artificial crystal is around, the thermal conductivity is very slow, the texture is rough, and the luster is not high.

How to distinguish the authenticity of crystals.

In terms of hardness, natural crystal is a combination of a variety of minerals, and its Mohs hardness can reach about that, while the hardness of artificial crystal is about that, in comparison, artificial crystal is easy to break.

At the same time, the naturally formed crystal is relatively rare, the surface is oily or glass luster, with a high gloss, gelatinous texture and grease are very strong, through the illumination of the light, there will be bright reflection, and the luster of artificial crystal is not high, it looks relatively mild.

In addition, natural crystal is a kind of mineral spar, which gives people a feeling of warm in winter and cool in summer, fast thermal conductivity, and more tactile feel, while artificial crystal is mostly made of glass, thermal conductivity is a little slower, and it doesn't feel good to the touch.

1. Light: The natural crystal is placed vertically in the sun, no matter which angle you look at, it can release a magnificent color. Fake crystals cannot.

2. Search with dicolor: natural amethyst has dichroism, and fake crystal has no dichroism.

3. Search with a magnifying glass: Search under the transmitted light with a ten-fold magnifying glass, and you can find that the foundation of the bubble can be determined as a fake crystal.

4. Tongue licking: Even on dog days in the hot summer, licking the natural crystal appearance with your tongue also has a cold and cool feeling. Fake crystals, there is no feeling of coolness.

5. Hardness: The hardness of natural crystal is large, and it will not leave traces of decay on the jewelry with crushed stone; If there are streaks, it is a fake crystal.

6. Search with a polarizer: 360 degrees under the polarizer is a natural crystal, and there is no change in the fake crystal.

7. See: In the process of formation, natural crystal always contains some impurities when affected by the situation, and when investigating against the sun, you can see a faint uniform and tiny horizontal stripe or catkins. The fake crystal is mostly smelted with crystal slag and glass slag, polished and colored, and there are no uniform stripes and catkins.

8. Detection with thermal conductivity meter: adjust the thermal conductivity meter to 4 green grids to test gemstones, natural crystals can rise to 2 grids of yellow, while false crystals do not rise, and rise to yellow grids when the area is large.

9. Search with hair: 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.

It can be identified as a natural crystal stone by the following methods:

1. Specific gravity, the weight is too light is fake with the file, which can exclude imitation products such as glass, plastic, and pressed particles, and the weight of the crystal on the market is almost the same as that of natural crystal, and the method of hand test is not easy to find the true or false;

2. Refractive index, put the crystal in a darker place, the color of the natural crystal will be very bright, and the color of the crystal will be relatively dull;

3. Color difference, natural crystal has color difference, a piece of natural crystal can not be every part of the color is very uniform;

4. Water, natural citrine can be distinguished in water, natural citrine is uneven in the water mess, usually a piece of color radiation to the whole crystal is yellow, and the crystal is uniform;

2. Refractive index, put the crystal in a darker place, the color of the natural water trace wide crystal will be very bright, and the color of the crystal will be relatively dull;

3. Color difference, natural crystal has color difference, a piece of natural crystal can not be every part of the color is very uniform;

4. Water, natural citrine can be distinguished in water, the color of natural citrine in the water is uneven, usually a piece of color radiates to the whole crystal is yellow, and the color of the hand-raising beam crystal is uniform;
