Jade identification "prescription" is not reliable
Jade identification "prescription" is not reliable
In the jewelry market, the crystal-clear mid-range jade jewelry that reflects the skin is especially popular among beauty lovers. However, some consumers used the "folk detection method" demonstrated by the seller to select jade, and later discovered that jade is a counterfeit. The reporter recently received a complaint about consumer shopping fraud, and in-depth investigation of the jade identification "rule" inside the folk.
On-site experiment buyers were fooled
Ms. Qiu, a member of the public, saw a “study†of a jade stall owner performing a natural amber identification in the Shenyang Road market. The stalls adjusted the brine proportionally and placed the bracelets of natural amber and glass in a container filled with salt water, while the hand string that originally sinked in the clear water container floated up in the brine. I heard that the floating bracelets are natural amber, and the stall owners let the promotion, Ms. Yan and several onlookers can not help but unpack. However, it has been confirmed by the professional testing institutions of this city that the “amber†bracelets purchased by Ms. Yan for more than 500 yuan are actually resin strings worth less than 10 yuan. Ms. Qi complained to the newspaper “Consumer Express – 3 to 15 hotline tonight†and said with anger: “These performances are really deceptive!â€
The reporter then unannounced visits to individual jewelry and jade shops in the city. More than half of the staff members claimed to be able to help customers identify the true and false jewelry. For example, the method of identifying natural amber is to use 1:4 brine; the method of identifying 宓皇玉 is to compare it with Hetian jade; to identify natural tourmaline can be verified by using paper scraping friction; the method of identifying jade is to use them to draw glass. and many more. When the reporter was dubiously saying that "resin bracelets can also rise in salt water", several female clerk impatiently said: "On the Internet, these methods are available!"
It’s not true that you’re not convinced
The reporter searched online for the identification method of jewellery and jade, and found the so-called "salt detection method", "friction electrification method", and even the magical folk "prescription" such as "detecting natural jade with a money detector". However, at the same time, some jewellery professionals posted on the Internet to attack this.
The professionals of this city's gemstone associations gave reporters a so-called "salt test method". Amber, lightweight plastics and resins can all float up. In the "electricity experiment", pure natural tourmaline bracelets can absorb paper after rubbing. Chips, but artificially injected tourmaline has the same effect; "draw glass" and with the money detector can not identify some of the artificially dyed jade. According to a number of professionals, even the senior industry insiders have a multi-practice approach to the identification of amber. The folk methods rumored on the Internet are very one-sided, and only a few fake materials such as glass can be removed. The "identification performance" of the merchants, ordinary people should keep in mind that "seeing is not necessarily true."
In response to the online testing method, Director Han Xiufang of the city's gemstone testing center told reporters that under normal circumstances, the detection of natural jade requires the assistance of professional instruments, and it is recommended that people go to the authority for testing. It is recommended that the public choose a regular business when purchasing jewelry and jade, and keep the invoice as the basis for rights protection.
