How to identify the authenticity of chalcedony How to identify the authenticity of chalcedony

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.

Methods of identifying the authenticity of chalcedony:

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

2.Touch feeling: Real chalcedony bracelets have a cold feeling when touched by hand, which is very smooth and delicate, while 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.Magnifying to see: magnifying glass observation: real chalcedony can not see impurities and cracks with the naked eye, and cracks and flaws can only be seen with more than 10 times magnifying glass, which means that it is true, and the quality is relatively high.

5.Find an expert: If you are really not sure whether it is true or false, you can find an expert for identification.

6.Observe more: Observe the luster of chalcedony, if chalcedony looks more aura and has a warm luster, then it can be preliminarily determined that it is natural chalcedony. If it is a fake chalcedony, not only does it look dull and have no aura, but it also has bubbles.

7.Hardness: Scrape the chalcedony with a knife, if there are no marks on the surface of the chalcedony, there is no scratch, then this kind of chalcedony is natural chalcedony, if there is a scratch it must be a fake chalcedony.

8.Weighing weight: We can judge the authenticity of chalcedony by weighing the specific gravity.

Hopefully, the above information will be helpful in answering your questions.

1. Look thoroughly.

Real chalcedony water head and feet, with waxy luster, although high transparency, but not as good as glass, it looks like watery, but with waxy luster, there is no lack of warmth. The fake chalcedony is head and foot, with higher transparency, showing the light of glass, lacking waxy luster and warmth, and it looks more beautiful and ** lower than the real chalcedony.

2. Look at the color.

Chalcedony has natural colors such as red, yellow, blue, purple, and pink, and these own colors are not single enough, and are mostly mixed with variegated colors, and the color is dull. The chalcedony of the fake is mostly processed and dyed, although the color is single.

1. Uniform, but lacking softness and gloss, it looks cold, hard, sharp, and too rigid. In addition, you can also weigh it, the weight is too light, it is likely to be a fake chalcedony made of plastic.

3. Look at the hardness.

The hardness of chalcedony is between, and if you scratch it on the surface with a sharp object, it will not leave scratches, because it has certain inclusions on its surface, and if you look at chalcedony with a tenfold magnifying glass, you can find cracks, impurities and flaws inside it. Fake chalcedony has few blemishes, impurities, etc., inside under the display of a magnifying glass, and it looks better textured.

Generally speaking, chalcedony can be faked, most of the fake ones in the market are optimized by artificial dyes, the effect of its wearing is not good, and it is not conducive to physical and mental health.

Chalcedony can be counterfeited due to the preciousness and rarity of chalcedony, in general, it can be faked, but it can be directly identified from the naked eye, usually the surface of real chalcedony is mainly grease luster or glass luster, high transparency, few internal defects, uniform and translucent color, and the fake color is blurred, the gloss is very low, and it looks more false.

Or distinguish by listening to the sound of percussion, the internal structure of natural chalcedony is relatively dense, hold it in the hand and tap it gently, if it makes the sound of the balance of the world, the limb sound is crisp and loud, it means that it is natural chalcedony, if the sound is low, it is a fake chalcedony.

At the same time, it can also be distinguished by weighing method, usually the natural chalcedony density is large, put the same volume of chalcedony in the hand and weigh it carefully, you will obviously feel that the chalcedony of the natural skin hail has a downward pressure feeling, and the fake one gives people a light and fluttering feeling.

1. Look at the luster: whether the real jade is translucent or opaque, it has a warm luster, and it is normal to have a small amount of impurities or cotton wool-like patterns inside, and the color of the fake jade is dry, gray and dull without aura, and some have bubbles.

2. Hardness: Cut and scrape with a knife, and the real jade leaves no traces.

3. Specific gravity: real jade feels heavy, and fake jade is light.

4. Listen to the sound: hang the jade with a thread in the air, and hit it with a hard object, the sound of the genuine product is crisp and pleasant, the aftertaste is melodious, and the fake one is relatively dull and dry.

5. Look at the fracture: observe with a 10x magnifying glass, the fracture of the real jade is uneven, and the relatively fine structure can be seen, the fracture of the fake jade is neat and shiny, often a glass imitation, and the fracture structure is rough and there is no waxy luster is a stone imitation.

<>1. Look at the moistness and luster.

The color of chalcedony is mainly reflected by the internal components, mainly red, yellow, blue, green, white, and blood, and the texture is translucent to white, and it is difficult to see the impurities inside with the naked eye. If the color of chalcedony is single.

1. Uniform, dry, gray, dull, lacking aura, with bubbles inside, it is likely to be a fake chalcedony.

2. Measure hardness.

The hardness of chalcedony is in between, and after being scratched on its surface with a sharp object, it will not leave scratches. Due to the different materials of fake chalcedony, there will be obvious marks after scratching. In addition, two pieces of chalcedony with the same volume and size, the one that feels heavy and cold to the touch must be real chalcedony, and the one that is light and fluttering without cold feeling when picked up is fake chalcedony.

3. Listen to the sound.

Hang the chalcedony with a thread and hit it with a metal rod, the sound of the real chalcedony is crisp and melodious, and the sound of the fake chalcedony is dull and dull. In addition, you can use a ten-fold magnifying glass to observe the fracture of chalcedony, the real chalcedony port is difficult to polish and smooth, not only looks uneven, but also can see the more delicate internal structure, the fracture of the false chalcedony is often neat and shiny or rough without waxy luster.
