Inside the testing center, there is the only science education base in Guangdong with the theme of jewelry. According to the staff, the education base covers an area of ​​more than 100 square meters, with more than 180 products and more than 70 kinds of jewels and jade. The exhibition hall is divided into 7 large areas. It can be opened to the public when appropriate. Visitors can also Experience some jewelry identification steps on site.

As a third-party testing organization, how to guarantee the credibility of the organization's testing? Is the certificate issued by the testing agency necessarily true? Will there be a shady scene inside?

There is no guarantee that 100% will not go wrong.

In the view of Dr. Guo Qinghong in the testing center, such concerns are not necessary. “First, the testing organization must be legally set up, and undergo a series of certifications, such as testing personnel, machinery and equipment, environment, methods and systems, etc. And not all The organization can test each project, and the relevant departments should evaluate the testing organization and obtain the professional qualification certificate before they can carry out relevant tests. This will ensure that the results we detect are fair and not biased towards either party."

In fact, the testing center detects thousands of types of jewellery every day. Even if the inspector works seriously, there are also possible errors, such as printing errors in the test certificate and misplacement of the sample photos. Guo Qinghong does not deny these possible existences. "It is inevitable that people will be exhausted when they do one thing repeatedly, but we must overcome the weakness of humanity itself."

In order to avoid such errors, the testing center has relevant regulations on the testing system and procedures, including how much time the inspector should take a break; in the testing process, the main inspection must be followed by a re-examination; the test results cannot be Only one person has the final say... This way, the chances of detecting errors are negligible. But even then, Guo Qinghong said that "there is no guarantee that the test will be 100% error-free."

With the continuous advancement of science and technology, various counterfeiting methods in the jewelry market are becoming more and more advanced. For example, CVD synthetic diamonds on the market are new varieties that have emerged in recent years. The emergence of synthetic gemstones is a big test for testing organizations. In order to detect a variety of emerging synthetic diamonds, the Jewelry Testing Center has also equipped a new imported advanced instrument for this purpose.

"Anything that is falsified is in front of us. There are fake things first. We will find out the method of discrimination based on the characteristics of fraud, and use routine testing." During the inspection process, the inspectors were reminded to play. Twelve points of spirit, because you may encounter new things at any time.

The inspection fee for a piece of jewelry can reach several thousand yuan

As a work that sounds like "high on", what is the charge for jewelry inspection?

According to Guo Qinghong, the jewellery testing center generally does not charge a lot of money. The average test is one hundred yuan, but for those jewels that are worthless or difficult to detect, the charge will be higher. "It is difficult to detect, and the value is very high. It can also cost several thousand yuan to detect a charge."

It is understood that the precious jewelry charging standard can be mutually agreed between the testing center and the tester. When consumers take jewelry for testing, the testing center first evaluates the difficulty and risk of detection. The so-called risk degree, that is, the higher the customer's jewelry value, the finer the workmanship, the greater the risk that the testing staff will bear during the testing process.

"Because inadvertently broke the jewelry, the testing center and the individual may have to pay compensation. If the value is very cheap, it is no problem to lose 10 times. If the value is very high, then how to pay? So the higher the value The greater the risk of jewelry,” Guo Qinghong said, so far, there have been no cases of damage to high-value goods.

At present, the jewellery and jade market in Guangdong mainly has the phenomenon of fake, shoddy, and lack of money. The main performance is the lack of color of precious metals, the level and the nominal inconsistency. For example, the jadeite that has been filled and processed is called "true color true jade", and the de facto falsehood is covered with the name on the name; the diamonds of more than 1 carat that can be sold after the rough stone classification is required are sold without classification. Deceive consumers for profiteering purposes.

Regarding the bad phenomenon in the jewelry market, Guo Qinghong repeatedly stressed that "I hope that the public must not buy high-value jewellery in the tourist area and buy high-quality jewellery. We still have to base on local consumption. Even if we finally find that there is a problem, we can Discuss a statement."

Guo Qinghong said that many people like to buy jewellery when they travel to Yunnan. In fact, the last thing they bought was from Guangdong. "The merchants in Yunnan have got goods from Guangdong, but the Cantonese people ran there again. I bought the goods back, and when I bought them, the price was much higher than this."

"We have also done some assessment work. Some people have bought more than 30,000 jewels from there, and come back for an assessment, which may be worth only 10,000 yuan."

Guo Qinghong also used his own personal experience to tell the story of “there are many pits” in the tourist area. During the 11th of last year, he visited the jewelry market in the tourist area. He used his professional knowledge to cut a piece of jewelry with a price of more than 10,000 yuan to 150 yuan. "But how can consumers cut down to 150 yuan? They have to pay more than a thousand yuan, and they have to earn several times more than a thousand."
