Print

Jewellery companies report that some gold alloy currently sold on market has low gold purity although gold-purity testing machines show a purity rate of 99.99 percent.

According to a representative from Sai Son Jewelry JSC, the impurities of this particular gold alloy will not show up on these machines.

Nguyen Van Dung, chairman of the HCM City Association of Fine Arts, Gold, Jewellery and Gemstones, said that his association had received information regarding this particular problem with gold alloy from its members.

Jewellery makers who bought the gold alloy discovered that it had a low rate of purity during the refining process, Dung said./.
