The Guitar, named Eden of Coronet, broke the Guinness Book of World Records when it was unveiled at the Baselworld fair. Aaron Shum Jewelry and Coronet Diamonds teamed up with Chow Tia Fook, designer Mark Lui, and Gibson Guitar to create the blinged out guitar. They designed a floral and nature motif with 1.6 kg of 18k gold and more than 400 cts. t.w. diamonds. Shattering the world record with its unique design and brilliant diamonds, the Eden of Coronet was well worth the effort. It is now considered to be the only piece of jewelry that can be played.
