The old counterfeiting trick, pickling jade is harmful to your body and your wallet! Is there really no way to distinguish?

Although jadeite has only been introduced to China for one or two hundred years, it is highly sought after by jewelry and jade lovers . However, natural , perfect jade is extremely rare. Many jades may appear flawless, but there are always some minor flaws that prevent them from being sold at a high price .

In order to make a profit, some people began to use inferior jade to make counterfeit jade, which is the origin of acid-washed jade . But there is really no point in buying acid-washed jade, and those acid washes may contain some chemical substances that affect human health . If you spend a high price to buy a piece of acid-washed jade, it is really not worth it.

What is pickling

Acid washing actually means soaking some defective jadeite raw stones in chemical reagents with strong acid washing properties to achieve some surface optimization effects. Some cracks will also become larger, and counterfeiters will fill them with some glue.

After these treatments, the flawed jade will become very pure visibly to the naked eye. This is to deceive some consumers who have no idea about the business, and jewelry does not enjoy the "three guarantees policy", that is, even if you find problems later, there is basically no possibility of return or exchange.

How to Identify Acid-Washed Jadeite

Weighing

As long as it is fake, no matter how well you make it, it will never become true. The biggest feature of acid-washed jade is that it is much lighter than natural jade and has a lower density. Under the same conditions, you can judge the authenticity of jade by weighing it with both hands.

Ultraviolet light observation

Anyone who has purchasing experience knows that the color of jadeite must generally be observed under the light . Some acid-washed jade will show up in this stage. When the acid-washed and glue-injected jade is illuminated by ultraviolet light, a layer of yellow-green fluorescence will appear . In addition, it is rare to find flaws in acid-washed jade, but " there is no jade without flaws ", and being too perfect is actually not perfect. In addition, the sound that acid-washed jade makes when tapped lightly will be duller than that of natural jade.

Color distribution

When defective jade is acid-washed to make fakes, the texture and color band distribution will inevitably be destroyed by the acidic solvent . If you observe carefully, you can easily find that the color texture of acid-washed jade has faults and gaps . If we come across jadeite that has been acid-washed and then injected with glue, we can easily find out through a magnifying glass that there are some fine bubbles in the injected part that are not present in pure natural jadeite . If you encounter this situation, just put it down gently and leave immediately when purchasing. Guo Kun's message:

When you come across jadeite that is extremely perfect when observed with the naked eye and is also very cheap. First, put away your desire to find a bargain and stay calm to avoid buying fakes. Because acid-washed jade will not only fade and turn yellow after wearing for a long time, but also because it has been soaked in chemical reagents, it is harmful to our body.
