The annual event was held this year in association with the Company of Master Jewellers and sponsored by Diamond Partner International Jewellery London and Gold Partners Tresor Paris and Bering.
The identity of those on the Hot 100 list is kept secret until the big reveal at the party, which this year had an emerald theme. Guests were treated to drinks and food at the event before an exclusive screening of photographs taken of each person in the Hot 100.
Entertainment continued into the night with music from the Redstone Collective, a Scalextric track sponsored by Pursuit and a photobooth sponsored by Clogau Gold.
A book packed with exclusive portrait photography and insightful interviews featuring this year's Hot 100 was given out at the event to guests and will be posted out to subscribers of Professional Jeweller with the October issue of the magazine.
