The new members are Bec Astley Clarke MBE, founder of Astley Clarke, and Dax Humberstone, managing director of Antwerp Diamonds, who will sit alongside recently appointed member, Mark Adlestone, chairman of Beaverbrooks, who joined earlier this year.
The trio will be on the board in the lead up to the September 2014 show held at Olympia, London.
Chairman and event director Sam Willoughby said: “We are thrilled with the new additions to the IJL advisory board. The role of the board is to capture senior level advice and valuable insight from respected members of the industry.
“It really helps the show team deliver an event that is relevant, exciting, profitable and engaging.”
