Due to the high popularity of the live broadcast room of anchor Zuo Yan, fans in Zuo Yan keep throwing out their own questions. After asking many die-hard fans in the live broadcast room in Zuo Yan, we received these different comments. Let's have a look.

Netizen @ Talking Frog: "If you are rushing to buy elegant heirloom jewelry, you'd better not report great hopes. Things with higher cost performance should also pay attention to a certain degree of price and goods, right? As long as the real thing is worth the money spent, don't think too much about others. "

Netizen @ _ Ting Qing: "Listen to my friend. I feel very ordinary after buying it. What shopping needs in this era is the refreshing feeling brought by pressing the payment moment. Things are not fake. It depends on what you want to buy. I don't feel Zuo Yan, the live content is ok, and the jewelry is different. "

Netizen @ 褽褽: "Zuo Yan went to see the diamond jewelry appraisal at his own expense. There is nothing to say about the quality of goods, but this attitude is much stronger than most anchors. "

Jewelry appraisal instrument

One: magnifying glass

Zircon is very similar to diamond and is the best substitute for diamond. The identification method is that zircon has polarization and large birefringence. Observing the processed zircon prism surface with a magnifying glass of 10 times, it can be seen that the bottom edge line has obvious ghost, but the diamond has no ghost phenomenon.

Two: portable microscope

Nowadays, with the development of science and technology, glass products are mostly counterfeit, which is often difficult for many old experts to distinguish with the naked eye. It is easy to distinguish glass products with the help of portable microscope (such as Ainiti, Diguang, etc.). ).

Because there are bubbles in the production process of glass products, we can clearly see the bubbles in the glass when we look at the glass products with a portable microscope and zoom in 200 times. So you can tell whether it is a glass product or not.

Three: Spectrometer

At present, there are many spectrometers used for jewelry identification. The Opal3000 Pro jewelry identification spectrometer, which enjoys science and technology again, improves the sample testing method of the original jewelry identification equipment, has an open sample operation platform, can measure various jewelry samples more conveniently and quickly, and is very suitable for laboratory use.

Four: pen spotlight flashlight:

Used to observe the transparency of dark gemstones. The electric beads of spotlight flashlight should be concave in the writing surface and not protrude from the writing surface, otherwise it is not easy to observe.

Because of its high value, investment prospect and non-renewable mineral resources, more and more consumers and investors pay attention to the jewelry market.

However, most consumers lack the knowledge and tools to distinguish between true and false, criminals often make high profits by shoddy goods, and buyers are prone to serious economic losses. A large number of fakes increase the risk of purchase and disrupt the market order. Therefore, it is extremely important to identify the authenticity of jewelry. Many pseudo-experts also took the opportunity to make profits.
