A major HK-listed jeweler's stock fell when gold content in some 18K gold products were removed from sale as it didn't meet Beijing Association on its content of gold. The HK jeweler's spokesperson was reassuring people in HK that these products were only found in Mainland stores. Given I'm not surprised as they have a very big HK customer base, their other competitors like Chow Tai Fook must be taking advantage on this news. Also many Chinese will travel from the Mainland to HK to go shopping, especially for jewellery. Just have a look at some of the photos what you normally see in a typical jeweler's.
