How to distinguish the real from the fake, how to distinguish the real from the fake

The methods for distinguishing the true and false chalcedony are as follows: 1. Transparency, natural chalcedony is mostly transparent, transparent in color, and has oil and waxy luster on the surface; The imitation chalcedony has a slightly lower color transparency, and the surface color is saturated and rigid, showing a glass-like luster. 2. Hardness, high-quality chalcedony has a hard texture, Mohs hardness is between degrees, and hard glass is used to scratch the surface layer lightly, which will not leave scratches.

Fake chalcedony is mostly gelatin-dyed ore, and scratching its surface with glass will produce deep marks. 3. Touch, chalcedony is a kind of cryptocrystalline quartz, its texture is as transparent as ice, put it in your hand to play, its temperature will not change with the temperature of your hand. The imitation chalcedony is not uniform enough, and there is no cold texture when you put it in your hand.

1.Look at the gloss. The chalcedony itself has a warm luster, and the fake chalcedony looks dry and gray and has no aura.

2.Feel. A real chalcedony bracelet has a cold feeling when touched by hand, which is very smooth and delicate, while a fake chalcedony has no cold feeling.

3.Transparency. Real chalcedony is translucent and has a crystal clear feeling, while fake chalcedony is not uniform enough and not crystal clear enough.

4.Observe with a magnifying glass. Real chalcedony can not see impurities and cracks with the naked eye, and cracks and flaws can only be seen when observed with a magnifying glass of more than 10 times, which means that it is true, and the quality is relatively high.

5.If you are really not sure whether it is true or not, you can find an expert for identification. Be cautious when buying to avoid being deceived.

Chalcedony can be distinguished from the fake by observing and examining the texture.

The color of real chalcedony is mostly gray, blue-gray or blue-gray, and the color is relatively uniform and there is no obvious color difference. If the color is too bright or the color distribution is uneven, it may be a counterfeit product. True chalcedony has a certain texture, such as a cloud, such as crab claws, etc.

If the texture is too monotonous or there is no texture, it may be a counterfeit.

The texture of real chalcedony is more delicate and has a certain oily texture. If the texture is rough or does not have an oily texture, it may be a counterfeit product. True chalcedony is usually less transparent and not too bright. If the chalcedony is very transparent, it may be crystal or some other counterfeit product.

Real chalcedony is harder and has some resistance to abrasion. If there is visible abrasion or scratches on the surface of chalcedony, it may be a counterfeit product. It should be noted that the above methods can only provide a certain reference, and the best identification method still needs to be identified by the appraisal agency of the nuclear industry.

If you want to buy real chalcedony, it is best to choose a regular channel to avoid buying counterfeit products.

Precautions for buying chalcedony

1. Material: The main material of chalcedony is quartz and siliceous minerals, and it is necessary to choose chalcedony with hard, crystal clear, no impurities and flaws to avoid affecting the appearance and quality.

2. Color: The color of chalcedony is generally white, gray, light yellow, etc., and it is necessary to choose uniform, natural and clear chalcedony to avoid color difference and fake and shoddy products.

3. Gloss: The gloss of chalcedony needs to be selected as good, natural and smooth chalcedony, and rough, dull, matte or over-treated products should be avoided.

4. Process: The production process of chalcedony needs to be fine, and it is necessary to choose chalcedony with good production technology and fine handwork to avoid defects and damage.

5. Brand reputation: choose a brand or merchant with the reputation of the forest to buy chalcedony to ensure quality and after-sales service.

The method of distinguishing the real from the fake with chalcedony: look at the transparency and look at the color.

1. Look at the transparency: although the transparency of chalcedony is very high, it does not reach the transparency like glass, and the whole chalcedony gives people a mellow feeling, and the luster is mostly waxy luster, with a certain sense of warmth; If it is glass, it is basically transparent, and the luster is cold, hard and sharp, and it will not give people a soft feeling; Plastic is even more fake, first of all, it is not right to touch the envy of the residual roll, it is very lightweight, there is no luster, and it looks very cheap.

2. Look at the color: Although our common chalcedony is colorless, the color of the speed of speech is very varied, so the dyed chalcedony often appears, but the dyed chalcedony color is dull, too harsh, there is no softness and gloss, and it gives people a fake feeling at a glance.

How to maintain chalcedony

Because pure natural chalcedony has heat dissipation, it is easy to lose water, and it is not easy to lose water if it is often worn, so it does not need to be soaked in water often, and it will be more and more ice penetration. However, in autumn and winter, the weather in the north is dry and less worn than ruined, it is best to soak in water regularly for 1-2 days (the colder the water, the better), and soon it will return to its original luster and moisture.

However, there is one thing to be careful about: be sure to take off a hot bath or hot spring before soaking in the hot spring. Because chalcedony is super sensitive to heat and does not tolerate high temperatures, if you take a hot bath for a few days in a row, or often work in an environment close to fire at high temperatures, the chalcedony pendant will dry out due to water loss and become less transparent.
