Hung had arrived on a flight from Hong Kong. Customs department officials said they had sent the stones for testing.

Meanwhile, HCMC’s market management agency on Tuesday confiscated 141 kilograms of Chinese jewelry of unclear origins without necessary documents at the Hoa Binh Market and An Dong Trade Center.

The agency took samples of the jewelry for tests.

The market raid follows findings in the US that children’s jewelry made-in-China was laced with cadmium – a highly toxic chemical considered carcinogenic and harmful to the kidney and bones.

Cadmium is a white metallic element used in alloys, electroplating, nuclear reactors, dental amalgams, pigments and electronics items.
