LISBON  - The world's most expensive chocolate went on display at a chocolate fair in Obidos in Portugal on Friday.

Priced at 7,728 euros ($9,489) and covered in edible gold, the limited edition of 1,000 bonbons was guarded by two uniformed men. The chocolate has a filling of saffron threads, white truffle, vanilla from Madagascar and gold flakes.

Its creator Portuguese chocolatier Daniel Gomes said the diamond-shaped chocolate was certified as the world's most expensive by the Guinness Book of Records, which in 2017 listed $250 La Madeline au Truffe made by Danish artisan chocolate-maker Fritz Knipschildt's as the record holder.

Its crown-shaped box is decorated with 5,500 Swarovksi crystals and also carries personalised pincers.

($1 = 0.8144 euros)
