They say that if it looks too good to be true, it probably isn't.
So the next time you go online to buy that glittering Tiffany bauble for your loved one, beware.
It was only a matter of time before the coveted American jewellery brand fell victim to the mainland's relentless counterfeiters.
However, after months of help from Hong Kong private investigators, mainland public security bureau officers have seized tens of thousands of fake Tiffany jewellery pieces with a value estimated at HK$92 million.
The raids on Monday in Guangzhou were carried out by police in co-operation with investigators hired by Tiffany to probe fakes, some sold online. The counterfeit Tiffany pieces, numbering about 80,000, were seized by the Economic Crime Investigation Department of Guangzhou Public Security Bureau at several locations, included a packing factory in a residential area.
The fakes are estimated to account for more than half the counterfeit Tiffany pieces selling globally, and are believed to have been aimed at customers in Hong Kong, the United States, Canada and Britain.
