Gold jewellery bought from tourist attractions may be just a craft. In the past weekend, the Guangdong Gold and Silver Jewelry Testing Center launched a two-day free testing event at the flagship store of Guangdong Gold Plaza, Haizhu Xinduhui Plaza. According to the on-site staff, there are far more people who come here to buy gold than to test it. However, from the daily inspection situation, the gold product qualification rate in the Guangzhou market is very high, and the problematic ones are basically bought in foreign tourist attractions.
According to Yang Yukun, deputy director of the training department of the Provincial Gold Jewelry Testing Center, “In the past tests, the purity problems are actually small probability events. The jewelry purchased in the formal channels has few general problems. Buying gold in irregular places Jewelry is very likely to buy copper alloy, the composition is mainly copper, the color looks very like gold, but there is no gold component. This is a kind of gold jewelry involved in more cases." He introduced, in the tourism market, buy In fact, it is mostly crafts, it is difficult to buy high purity jewelry.
He also introduced that in daily testing, the testing center will first determine the testing cost based on the difficulty of sample testing, usually starting from 100 yuan / piece. Test results are generally accompanied by a certificate, if the oral conclusions, the test fee can be reduced by 50%. The detection means are basically non-destructive testing, and the inlaid gold jewelry does not need to be disassembled. Partially thick samples require destructive testing.
Yang Yukun reminds consumers to pay attention to four certifications for the purchase of jewelry: measurement certification mark, quality inspection station authorization mark, international mutual recognition mark, national laboratory approval mark.
