All eyes were on precious metal jewellery at Sublime Shine: Metal Innovations in the Art of Jewellery – a special exhibit at the Hong Kong Convention and Exhibition Centre section of Jewellery & Gem WORLD Hong Kong (JGW) 2025.

Organised by Informa Markets' Jewellery & Gem Knowledge Community, the showcase was dedicated to gold, platinum, silver and other metals used in fine jewellery manufacturing.

It was supported by Industry Partners World Gold Council (WGC) and Platinum Guild International (PGI^®), Premium Sponsor Yuen Kee Bullion Co Ltd, and Sponsors Osmium-Institut and Hatta New World Co Ltd.

Visitors to Sublime Shine discovered the universe of precious metals while exploring their ancient origins, cultural significance and the art and science behind metalsmithing. The exhibit also demonstrated how state-of-the-art technologies can help jewellery manufacturers explore cost-effective production alternatives while remaining competitive in the market.

The showcase featured 10 special sections, from historical use of metals in jewellery to metal deposits from around the world, secret recipes of alloys, behind the scenes of jewellery manufacturing, precious metal markets and ethical sourcing, among others.

Highlights of the exhibit were live demonstrations on goldsmithing by Yuen Kee Bullion, and granulation and casting by Janus Ng, founder and director of 5Plus2 Design Lab.

Other activities included a photo booth as well as a charity sale, proceeds of which will be used to support jewellery education and appreciation initiatives, according to the organiser.
