Defying the truth, there are tricks to teach you to see amber
Amber has received the attention of consumers in recent years, but in the face of the mixed amber market, consumers are extra cautious when choosing amber jewelry, but still do not know whether the amber jewelry they bought at a big price is true or false? There are also many methods for identifying amber, such as using fire, cutting with a knife, or even verifying with a money detector. It is impossible to really determine the true and false of amber. So what should we do?

Zhang Wei, deputy chief engineer of the National Jewelry Quality Supervision and Inspection Center, used Chinese medicine as a metaphor to clarify the characteristics of amber and the difference with imitations by using four methods: "looking", "smelling", "ask" and "cutting". The scientific perspective guides consumers to tell how to tell the truth of amber.
Eye view
This is a trick to identify true and false amber; true amber texture, color depth, transparency, refractive index, etc. will change with observation angle and illuminance. This feeling is not found in any other substance. Just as we identify true and false people, such as superb artists can create a vivid figure of the wax, "just to the real thing" is just to talk about, even the best wax can not escape our eyes. Amber is transparent but very moist, not as unobstructed as glass, crystal, or diamond.
Hand touch
Amber is an organic gemstone that is warm and light to the touch, which makes it distinguishable from glass.

odor
The smell of natural amber is very special – natural amber gives off a pleasant resin odor when rubbed, heated or burned. This basic trait can help identify amber.
sound
A non-inlaid amber chain or bead placed in your hand will give a soft, slightly dull sound. If the sound of plastic or resin will be crisper.

Scratch sample
Scratching the surface of the natural amber produces a fine powder, while the surface of the imitation of the scratched plastic is spirally scratched. Natural amber is easier to powder than synthetic resin blocks. If there is a large, rare and precious inclusion in amber, it is likely to be imitation. One of the characteristics of optimized amber, including those with inclusions, is that they only have a bright color on the surface, while the inside is almost colorless.

Price determination
Amber raw materials are precious – if its price is much lower than the current market price, we must realize that it may be a replica.
At the same time, in order to verify the authenticity of the civil identification methods provided by the vast number of consumers, Zhang Wei and the moderator, respectively, carried out experiments on several identification methods proposed by everyone:
The test sample is soaked in saturated saline, the fake amber will sink to the bottom of the cup, and the true amber will float above the cup. This method is reasonable, but it also has great limitations. It is not suitable for precious beeswax. The reason for amber float is that the density of amber is finer, so it will float in saturated brine, but it is worth noting that there are many plastics that float, and styrofoam is an example.

At the end of the program, Zhang Wei, deputy chief engineer of the National Jewelry Quality Supervision and Inspection Center, also said that many methods of the folk can identify the true and false amber on one side, but they all have their limitations, and the materials of the fake are very different. Therefore, simple experiments may not detect the true and false of amber. In addition to accumulating amber knowledge and experience, the use of scientific identification methods, through precision instrument testing, is a reliable guarantee for the identification of amber.
