How to tell if a diamond is real or fake, how to tell if a diamond is real or fake

1 Ha gas test: You can take a breath on the diamond, if the water vapor on the diamond disappears immediately, it is a real diamond, and if the water vapor stays on the diamond for a few seconds before disappearing, it is an imitation.

2 Water Drop Test: Drop a drop of water on a diamond, if the water droplets remain spherical for a long time, it indicates that the diamond is real, and if the water droplets spread out in a relatively short period of time, it is a imitation.

3 Test with an oil-based pen: Use a special pen or ballpoint pen with oil-based ink to tell you how to distinguish a diamond from a fake, draw a line on the diamond countertop, if you leave an uninterrupted straight line, it means that the diamond is real. On the other hand, if there is a broken dotted line left at the underline, it indicates that it is an imitation.

However, testing with this method requires a magnifying glass.

4 White paper scribing test: Draw a black line on the white paper, put the countertop side of the diamond on that line, if you can't see the line, it means that the diamond is real, if you can see it, it's fake.

5 Look at the adsorption test: how to distinguish the real from the fake diamond? Diamonds have strong oil and dirt absorption, and when you touch the diamond with your fingers, you will feel sticky and sticky. This is something that no other gemstone has. In this way, it is necessary to strengthen the touch sensation of the trained fingers.

6 Diamond luster test: Comparing a well-cut diamond with a counterfeit under 100 degrees of incandescent light, it is easy to compare which diamond has diamond brilliance. However, this method should not be performed when it is too dark or too brightly lit.

7. Use the same instrument used to detect the authenticity of the diamond.

How to easily identify the authenticity of a diamond?

The beauty has two one-carat diamond rings, one real and one fake, and Longteng Xiaojie teaches you to quickly identify.

1.Look at the girdle of the diamond. If the girdle of the diamond is sand-polished, this method is most suitable. Because diamonds are harder than any simulants and do not have thin lines like simulants, diamonds have a grainy appearance around the girdle.

2.Diamonds are harder than imitations, and the faceted edges of imitations tend to be blunter than diamonds, and the faceted edges of diamonds must be sharp.

3.Because diamonds are harder than imitations, the faceted edges of imitations are often worn.

4.If a diamond has a natural surface, there is a chance to find the diamond's distinctive "triangular growth line" on the natural surface.

5.If a diamond is broken, it usually has a trapezoidal appearance, while imitations are curved or shell-shaped.

Considerations for buying diamonds.

1.Try to spend locally.

In fact, the quality of diamonds has little to do with the place of origin, and the public should change the consumption concept of "good quality and low price". When buying diamonds, don't be superstitious about where they come from. It is better to base itself on local consumption. When encountering problems, it is easier to complain and defend your rights.

2.Look at the test certificate.

When purchasing, carefully check whether the product has an appraisal certificate issued by an authoritative organization. It is recommended that the public buy goods in regular shopping malls in order to check the relevant quality inspection reports and product marks. If they suspect that there is a quality problem, they can save the evidence and complain according to the prescribed channels.

When buying jewelry, be sure to ask the merchant for the appraisal certificate issued by an authoritative jewelry and jade appraisal agency, and check the contents of the certificate one by one, such as **, whether the quality is consistent with the real thing, the signature of the appraiser, the date of identification, whether the content is filled in clearly and whether there are omissions, etc.

Summary. 1. Magnifying glass inspection: Use a magnifying glass to inspect the surface of the gemstone, a real diamond will show the honeycomb structure inside, if it is fake, it will have a smooth surface.

2. Water immersion inspection: Immerse the gemstone in clean water, the real diamond will quickly enter the clear water, and the counterfeit will show a slow and floating speed. 3. Price comparison check:

Looking at the diamond price comparison, the real diamond will have a very high and even price, while the counterfeit diamond will have a significant deviation. 4. Hot melt test: the gemstone is melted in the melting agent, the real diamond will not be melted, and the counterfeit will be melted away quickly.

Excuse me, but please go into more detail?

1. Magnifying glass inspection: Use a magnifying glass to inspect the surface of the gemstone, a real diamond will show the honeycomb structure inside, if it is fake, it will have a smooth surface. 2. Flooding inspection:

When the gemstone is immersed in clean water, the real diamond will quickly enter the water, while the counterfeit diamond will show a slow and floating speed. 3. Price comparison check: check the price comparison of diamonds, real diamonds will have a very high and uniform price comparison, while counterfeit diamonds will have obvious deviations.

4. Hot melt test: the gemstone is melted in the melting agent, the real diamond will not be melted, and the counterfeit will be melted away quickly.

Summary. Diamond ring authenticity identification method: 1

The easiest and easiest way for ordinary people to identify the authenticity of a diamond is to observe it with the naked eye. Naked eye observation is mainly to observe the "fire" of the diamond, that is, the diamond can reflect a variety of colored light, basically blue light. The more perfectly cut a diamond, the more dazzling the "fire" becomes.

The brilliance of imitations with high refractive index will appear stiff and dull. 2.When buying loose diamonds with hand touch, you can touch the surface of the diamond with your hands to see if there is any stickiness.

This is mainly due to the fact that real diamonds have an affinity for oiliness, and you will feel a sticky feeling when touched by hand. 3.Temperature-sensitive diamonds have the property of "high thermal conductivity", so we can see if the diamond has temperature or not.

If you hold the diamond close to your arm or face, you can feel a little warm. If it is a fake imitation, it will not have the heat transfer effect of a real diamond, but will be cool. 4.

Exhale to distinguish authenticityWhen buying a diamond, you can also exhale at the same time on the surface of the diamond and the imitation diamond, and the water mist condensed on the surface of the real diamond will evaporate faster than the water mist on the imitation diamond. Of course, this method of identification requires a diamond imitation to be carried with you in advance as a counterpoint for the experiment.

There are four kinds. Can you elaborate on that a little bit more?
