In its annual industry seminar at China International Jewellery Fair 2011, leading gem lab International Gemological Institute (IGI) urged traders to adopt a policy of full disclosure. In an era of information overload, it is vital to have the best and most credible product information. China's premier jewellery show runs through November 27. %% IGI's Guest speaker, Texas-based gem consultant and educator{{ John Pollard}} says, "It's a new world! Modern networking and information-sharing empowers consumers to learn the most complex details about diamond and jewelry buying. Retailers now have to recognize that improvements in staff-education, disclosure and awareness of future value are becoming increasingly critical to making sales." %% IGI's Hong Kong-based CEO{{ Marc Brauner}} opened the seminar, noting that IGI has participated in the Beijing fair for six editions now. "Everyone can see the industry continues to experience tremendous growth, however, the way the world is currently changing calls for caution and focus," he said, "especially with increasingly sophisticated consumers demanding more precise information on what they purchase." %% This year's talk, like earlier ones in the series, targeted owners and sales managers of major jewelry retailers from across China, focused on marketing and sales training. Addressing emerging training issues, Pollard demonstrated the different ways staff can confidently discuss products in ways that satisfy current customers, but also future customers with their eye on celebratory events to come.%%
