How to identify the authenticity of agate? How to identify the authenticity of agate

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, which has a delicate texture, fine structure, high hardness, large specific gravity, and a smooth and oily feeling to the touch. Fake agate is generally made of glass and plastic, with low hardness, light specific gravity, and a light or dry feel.

3. Look at the weight. 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.

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.

Agate is one of the more valuable gemstones. As an ornament, there are many kinds of agate, such as: rings, necklaces, bracelets, earrings, etc., and its colors are red, blue, and green. From the perspective of customs, European women prefer blue, Chinese women prefer red, and Southeast Asian women prefer green.

Purchase method:( Material. False nuance is imitated with other stones, characterized by its soft material; The texture hardness of real agate can reach 7 grades, while fake agate generally only has 5 grades.

With jade, you can make marks on fake agate, but you can't draw real ones. This is even more evident with instrumental identification. Judging from the surface texture, the broken ballast or compound eyes of real agate are not bright, while the imitation fake agate is shiny and has many bubbles.

From the point of view of grade, high-quality high-end products are selected when using materials, so there are generally no or few defects, while there are more defective products on defective products.

Color. The color of real agate is bright, pure, and harmonious, while the color of false agate is poor. When the two are compared, the flaws are exposed.

At the same time, you can also look at the texture. Most of the fake agate chimneys imitated with other stones have a petal-shaped pattern at the bottom, commonly known as "chrysanthemum bottom", but the real ones are not.

Workmanship quality. High-quality agate, because the production process is relatively advanced, the operation is strict, so the surface is bright, firm, Zhouzheng, no cracks. Inferior and low-grade goods are the opposite.

Styling with manufacturers. High-quality agate jewelry is generous and beautiful. Defective products are not so beautiful and generous in terms of lines, angles, thickness and other aspects.

In addition, brand-name manufacturers generally have a good reputation, excellent quality and reliable quality, while those illegal operators use defective products or take fake means to cheat money.

Good luck and happiness!

Look at the hardness. Real agate is harder, use a knife to scratch the surface of real agate, it will not leave scratches; False nuances, on the other hand, can leave traces.

Look at the texture. The texture of real agate is delicate, the hardness is high, the specific gravity is large, and the hand has a smooth and oily feeling; Fake agate generally has a small hardness, light specific gravity, and a smooth or dry feel.

Look at the bubbles. If you look closely with a magnifying glass, agate is a natural mineral and will not have bubbles; If it contains air bubbles, it is false.

Look at the stripes. True agate is generally striped and more natural; False stripes are more even.

Check the temperature. Agate is a highly energetic substance that is warm in winter and cool in summer. False agate changes with temperature.

Look at transparency.

True agate is translucent or opaque, the transparency is somewhat chaotic, and some can see the natural waterline; Fake agate has good transparency and no sense of hierarchy.

Look at the colors. The color of real agate is layered, and if you look closely at the strips, the real product will have densely arranged small red spots; Artificially dyed agate will fade over time.

Look at the head. True agate contains different minerals or impurities to form landscapes, waterlines, and flaws such as aquatic plants; Fake agate heads are better than real agate, but it is difficult to form floating colors, waterlines, and find flaws.

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

Most of the fake agate stone chimneys imitated by stone are petal-shaped patterns at the bottom, forming a "chrysanthemum bottom".

The dyed blue agate stone is bright and uniform in color, giving people a false feeling. Agate stone is divided into natural color and processed dyeing, and the natural color is mainly red, amber and white. The best blue and purple agate stone jewelry on the market is not a natural color, it is dyed after processing, and it will fade after a few years.

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

3. Process quality: The production process of high-quality high agate stone is strict and advanced, so the surface brightness is good, the inlay is firm and weekly, and there are no scratches and cracks.

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

5. Weight: True agate stone jewelry is heavier than synthetic agate stone jewelry.

6. Temperature: The real agate stone is warm in winter and cool in summer, while the artificial agate stone changes with the outside temperature.

Summary. How to identify the authenticity of agate for you: Check the hardness of agate with a knife:

Real agate is generally harder, and scratching it on its surface with a knife will not leave scratches, while glass products can leave traces, depending on the complexity of the workmanship of agate: if it is a genuine agate, the carved pattern is complex and exquisite, and the value is higher. Because agate stone is hard and lubricated, it is not suitable for carving.

See if there are stripes: Real agate generally has stripes and are more natural, while fake ones are more even.
