Winners of the 15th Hong Kong Jewellery Design Competition were announced ahead of the annual HKTDC International Jewellery Show. Responding to growing demand for gemstones in Asia, the HKTDC will launch a new show dedicated to raw stones at the AsiaWorld Expo on 3-7 March 2014, which enhances the 5-9 March fair that was already the world’s-largest Spring jewellery trade gathering.
