Studded with 400 carats of diamonds set in 18-karat gold, the Guinness world record-holder of the most valuable guitar first dazzled the world at Basel World in March 2015. Designed by Hong Kong songwriter and designer Mark Lui, the instrument is the result of more than 700 days of work from a team of 68 people. With an estimated value of about $2 million, it will be displayed together with some of the world's biggest and most valuable precious stones at the expo's jewels and diamonds pavilion.
