How to identify old agate, how to identify agate

1 Due to the greater attention to jade and jadeite in the society, the collection of old agate is less, and in recent years, the old agate has become popular, and there are many new and old agate products on the market. Generally speaking, the processing of old agate artifacts is manual, while the modern old agate is drilled with instruments, so the hole is relatively rounded, and the processing of old agate will leave some manual marks.

2. The most common material for counterfeiting old agate is glass, and there will be a small amount of bubbles in the glass products if you look closely.

3. The color of the old agate is relatively bright and the surface luster is better, while the real old agate will be a little dull due to the oxidation of the air, similar to the matte effect.

4 Counterfeit fake agate has a soft texture, and jade can be used to scratch traces on fake agate, while real agate will not.

5. True agate is warm in winter and cool in summer, while synthetic agate changes with the outside temperature, it becomes hot when it is hot, and it becomes cool when it is cold.

6. True agate can see the ribbon or filamentous "cloud" in it, and the transparency is worse than that of synthetic agate, while false agate is more transparent like a glass ball.

The most significant sign that distinguishes natural agate from fake agate is that its cross section has a concentric layered structure, using this sign, the whole agate is easier to identify, and the finished product after cutting, because there is no neat and obvious pattern, it is easy to make mistakes. But generally speaking, natural agate feels cool, the surface is like coated with a layer of wax, and has the luster of wax, translucent, hardness in Mohs 7, carved with a knife, because it is a crystalline body formed in a molten state, mostly spherical, so it is particularly dense; The surface is more delicate after grinding, and it is rubbed more than a dozen times on the hard miscellaneous wooden board, the agate is not hot, but the wooden board is hot; The color is often mixed together to form a beautiful pattern, layered pattern, brocade and other gorgeous and colorful patterns.

In addition to artificial synthesis, part of the fake agate is made of high-quality stone. Its basic characteristics are: although the feel is cold, there is no waxy feeling and luster, some have low hardness, and traces can be carved with a knife; Smashing the observation section, in addition to the lack of layers of agate, the particles are coarse, and there are even cracks; Opaque and clearly demarcated between colors.

Some unscrupulous traders stick a thin layer of organic matter on the surface of counterfeit agate, giving people the illusion of waxy luster and feel, so special attention should be paid when identifying.

The method of identifying old agate is as follows:

1. Color: real agate color is bright, delicate and bright, the color and light of false agate are poor, the contrast between the two is obvious, the color of natural agate is distinct, the strip is obvious, careful observation, the dense arrangement of small spots can be seen in the red strip;

2. Texture: Fake agate is imitation of stone, soft texture compared with real agate, and traces can be drawn on the fake agate with jade, while the real product can not be drawn;

3. Workmanship: The production process of high-quality agate is strict and advanced, the surface brightness is good, the inlay is firm, Zhouzheng, no scratches and cracks;

4. Temperature: real agate is warm in winter and cool in summer, and synthetic agate changes with the outside temperature, the weather becomes hot, and the weather becomes cool.

Identification method of real and fake agate: 1. Look at the color. In general, in general, the color is pure and the texture is clear on real agate; The color is dull and the coherence is false agate.

2. Look at the texture. The essence of agate is colloidal dehydrated silica, its texture is fine and greasy, the structure is fine, the hardness is high, the specific gravity is large, and the hand has a smooth and oily feeling. Fake agate is generally made of glass and plastic, with low hardness, light specific gravity, and a smooth or dry feel.

3. Pay attention to the amount of slippage. Real agate jewelry is a bit heavier than synthetic agate jewelry. 4. Look at the temperature.

Agate is a highly energetic substance that is warm in winter and cool in summer. Substances such as glass, on the other hand, look like agate, but they do not have this property. For example, in winter, the agate is slightly cool, and the cold and biting glass is glass.

5. Look at the water head. Mature natural agate has a water head, but the transparency is different, with different minerals or impurities to form aquatic plants and other landscapes, waterlines, flaws, although these impurities, flaws, etc. will reduce the value of natural agate, but it is also a proof that agate is natural; Whereas, the artificial agate has almost no blemishes and good transparency.

To distinguish the authenticity of agate, according to experience, it can be summarized in three words: see, feel, and recognize.

One look: look at the texture, look at the color. Agate on the hand to see whether its color is transparent, whether the color is uniform, because natural agate can not be without flaws, cracks can not be at all, through more than the flesh indicates that the texture is not pure, not transparent at all, indicating that it is fake.

The top is real agate, and the bottom is fake agate.

Second sense: touch the texture and weigh the weight. The appearance of the nine-mouth material is delicate and the porcelain is really swimming, oily, mostly persimmon red, the bottom of the light is slightly transparent, and the stone is very strong.

Three Senses: Knowing Completeness. No cracks do not protect the mountain, many of the current Baoshan materials are carved after vacuum glue injection, and the complete material is very rare. The fewer blemishes and cracks, the higher the value.

Identification of agate:

Color: The color of real agate is bright and bright, and the color and light of false agate are worse, and the contrast between the two is more obvious. The natural red agate is distinctly colored, and the bands are very distinct, and if you look closely, you can see the dense array of fine red spots in the red bands.

Most of the fake agate chimneys imitated by stone have petal-shaped patterns at the bottom, forming a "chrysanthemum bottom"; The dyed blue agate is bright and uniform in color, giving people a false feeling.

Texture: Fake agate is mostly imitated by stone, softer than real agate, and traces can be drawn on the fake agate with jade, while the real product can not be scratched. On the surface, real agate has few flaws and more inferior quality.

Transparency: The transparency of real agate is not as good as that of artificial synthesis, slightly chaotic, some can see the natural waterline or the "clouds", while the transparency of the agate made of artificial combination is good, as transparent as a glass ball.

If you want to identify agate, you must identify it from the pattern of its outer close, and in addition, you should also look at it from the feel, and the other thing is the color.

Agate can be identified mainly from the pattern color, texture, transparency, and weight. The surface of high-quality agate is bright and has a layered stripe pattern, while the fake agate is not bright enough and the color is too single. Superior agate is harder and has fewer surface defects, while fake agate is softer than imitation socks and is prone to scratches.

Real Agate has a lower transparency, whereas False Agate has a higher transparency.

The price of agate stone is not fixed, it is hierarchical. If it is an ordinary quality agate stone, like the size of an egg, it is about 10-20 yuan a gram. Madagascar's small agate rough, then its ** will be a little more expensive.

Because this kind of agate stone is more beautiful than many agate stones, a small reputation of the ** is about 20-40 yuan a gram.

How to identify agate? Well, the weight of his lightness, the weight of its color, and then from its texture can be seen.

Look at the material and the delicacy, as well as the color.

Methods for identifying agate:

1. Identify agate rough: check the hardness of agate with a knife, check the complexity of agate's workmanship, see if there are stripes, whether there are bubbles, feel the weight of agate, real agate is warm in winter and cool in summer, check the color of agate and other methods, can help you identify agate rough.

2. See if the agate rough stone has stripes: the real agate rough stone generally has stripes, and it is more natural, while the fake and shoddy stripes are more uniform.

3. See if there are bubbles in the agate rough: put the agate rough in a relatively blank place, carefully observe with a magnifying glass, if it contains bubbles, it means that it is fake.

4. Check the hardness of agate with a knife: the real agate rough will generally be hard, and a gentle scratch on the surface with a knife will not leave scratches, if there are scratches, it means that it is fake.

5. The complexity of the workmanship of agate: because the texture of the agate rough is relatively hard and lubricated, it is not so easy to carve, but if it is a real agate rough, the carved pattern is complex and exquisite, and the value will be relatively high.

Analysis: Agate stone has natural color, but also after processing and dyeing. The main natural colors are red, amber and white.

Among them, red is the best. The best blue and purple agate jewelry on the market is not a natural color, it is dyed after processing, and it will fade after a few years. Most of the dyed agate is naturally variegated and is not easy to be processed directly into jewelry.

How to distinguish real and fake agate jewelry? It can be identified in three ways.

Transparency: The transparency of real agate is not as good as that of synthetic agate, it is slightly chaotic, and some can see natural waterlines or "clouds", while synthetic agate has good transparency, as transparent as a glass ball.

Weight: Real agate jewelry is a bit heavier than synthetic agate jewelry.

Temperature: Real agate is warm in winter and cool in summer, while artificial agate changes with the outside temperature, it becomes hot when it's hot, and it gets cooler when it's cold. How to choose agate jewelry?

The first thing to do is to choose a color according to your liking. Red agate jewelry is the most valuable, such as choosing an agate necklace must pay attention to the color of each bead to be the same, no variegation, the size of the beads should be appropriate, but also pay attention to the finish to be good. Then, lift the necklace to see if it is vertical, whether each bead hangs on a line, if the necklace is bent, it means that some beads are off the eye, and the processing technology is rough.
