(IDEX Online) - New dates have been announced for two Hong Kong jewelry shows after they were twice postponed because of coronavirus.The Hong Kong International Jewellery and Diamond Show and its sister event, the Gem & Pearl Show, are now due to take place on 3 to 6 August, with extra Covid-19 precautions.They were originally scheduled for 2 to 8 March, were put back to 18 to 21 May because of Covid-19 and have now been moved back to August.Visitors to the venue, AsiaWorld-Expo, will have to enter through an installation that checks their temperature and sanitizes clothes and carried items. The first postponement was because of the Covid-19 pandemic. The second came after the Hong Kong government required visitors from any country other than China to quarantine themselves for 14 days. Irene Chan, CEO of AsiaWorld-Expo Management, said staff uniforms and surfaces at the conference centre will be sterilised using a light-based coating, which can prevent the growth of microbes for up to 12 months.The air will be purified and the venue disinfected with a wide-spectrum liquid sanitiser that kills both viruses and bacteria.
