Emerald, a hot gem in the jewelry industry, has a certain value whether it is collected or worn, so it has been loved by many friends. But in the process of buying jade, inexperienced people are often drugged. Of course, this is not necessarily a matter of experience. Many old players who claim to be experienced have also been drugged. This is because the counterfeiting technology is constantly updated! Let's take a look at some methods of counterfeiting:

First, rinse

Rinsing refers to soaking jadeite with strong calculation to wash off the mottled color inside and make jadeite dirty and white. The jadeite produced in this way is called B goods. After rinsing, dyeing or rinsing, dyeing and glue injection, it is called C goods and B+C goods.

Although B goods are cheap, they will lose their luster and then turn yellow after being worn for a long time. They have no value of preserving and increasing value. Do you think products C and B+C will be better?

Second, coating

Coated jadeite, also known as' dressing jadeite' and' toning jadeite', is to coat or spray a layer of green glue on the surface of jadeite to wrap the jadeite with lighter color, making it look darker and moist, with strong camouflage and deception.

Third, baking color.

The so-called baking method is to change the original color of jadeite by heating treatment, so that it becomes red. The natural red fly produced naturally is very small, and it is mostly brown-brown mixture. But after heating treatment, a better red color can be obtained.

Fourth, synthesis.

As early as 1984, the technology of synthesizing jadeite from sodium, aluminum and silicon dioxide was available in the United States, and the hardness and density of the synthesized jadeite were basically the same as those of natural jadeite, which was quite deceptive. Everyone must look for the appraisal certificate of the authoritative appraisal institution to avoid being deceived.

Verb (abbreviation for verb) forgery

Where there is synthesis, there is fraud. There are many jadeites imitated by glass in the market, but the gap between glass and jadeite is still relatively large. You can tell by observing whether there are bubbles and structures.

The color of your bracelet is average, airtight and green. It's not a big problem to play with yourself, and it's not afraid of collectible value. Generally, the profit of jadeite in jewelry stores is at least 2-3 times. So you can estimate the value of your bracelet according to the price you bought.
